When splitting a port, different local ports need to be mapped on different
systems. For example:
SN3700 (local_ports_in_2x=2):
* Without split:
front panel 1 --> local port 1
front panel 2 --> local port 5
* Split to 2:
front panel 1s0 --> local port 1
front panel 1s1 --> local port 3
front panel 2 --> local port 5
SN3800 (local_ports_in_2x=1):
* Without split:
front panel 1 --> local port 1
front panel 2 --> local port 3
* Split to 2:
front panel 1s0 --> local port 1
front panel 1s1 --> local port 2
front panel 2 --> local port 3
The local_ports_in_{1x, 2x} resources provide the offsets from the base
local ports according to which the new local ports can be calculated.

100GbE Intel Wired LAN Driver Updates 2019-05-02
This series contains updates to the ice driver only.
Anirudh introduces the framework to store queue specific information in
the VSI queue contexts. This will allow future changes to update the
structure to hold queue specific information.
Akeem adds additional check so that if there is no queue to disable when
attempting to disable a queue, return a configuration error without
acquiring the lock. Fixed an issue with non-trusted VFs being able to
add more than the permitted number of VLANs.
Bruce removes unreachable code and updated the function to return void
since it would never return anything but success.
Brett provides most of the changes in the series, starting with reducing
the scope of the error variable used and improved the debug message if
we fail to configure the receive queue. Updates the driver to use a
macro instead of using the same 'for' loop throughout the driver which
helps with readability. Fixed an issue where users were led to believe
they could set rx-usecs-high value, yet the changes to this value would
not stick because it was not yet implemented to allow changes to this
value, so implement the missing code to change the value. Found we had
unnecessary wait when disabling queues, so remove it. I,proved a
wasteful addition operation in our hot path by adding a member to the
ice_q_vector structure and the necessary changes to use the member which
stores the calculated vector hardware index. Refactored the link event
flow to make it cleaner and more clear.
Maciej updates the array index when stopping transmit rings, so that
process every ring the VSI, not just the rings in a given transmit
class.
Paul adds support for setting 52 byte RSS hash keys.
Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
since the interrupt handlers will handle resetting the bit, if
necessary.
Tony adds a missing PHY type, which was causing warning message about an
unrecognized PHY.

GCC 8 contains a number of new warnings as well as enhancements to existing
checkers. The warning - Wstringop-truncation - warns for calls to bounded
string manipulation functions such as strncat, strncpy, and stpncpy that
may either truncate the copied string or leave the destination unchanged.
In our case the destination string length (32 bytes) is much shorter than
the source string (64 bytes) which causes this warning to show up. In
general the destination has to be at least a byte larger than the length
of the source string with strncpy for this warning not to showup.
This can be easily fixed by using strlcpy instead which already does the
truncation to the string. Documentation for this function can be
found here:

In some cases when a queue related allocation fails, successful past
allocations are freed but the pointer that pointed to them is not
set to NULL. This is a problem for 2 reasons:
1. This is generally a bad practice since this pointer might be
accidentally accessed in the future.
2. Future allocations using the same pointer check if the pointer
is NULL and fail if it is not.
Fixed this by setting such pointers to NULL in the allocation of
queue related objects.
Also refactored the code of ena_setup_tx_resources() to goto-style
error handling to avoid code duplication of resource freeing.

This patch introduces "recovery mode" to the i40e driver. It is
part of a new Any2Any idea of upgrading the firmware. In this
approach, it is required for the driver to have support for
"transition firmware", that is used for migrating from structured
to flat firmware image. In this new, very basic mode, i40e driver
must be able to handle particular IOCTL calls from the NVM Update
Tool and run a small set of AQ commands.
These additional AQ commands are part of the interface used by
the NVMUpdate tool. The NVMUpdate tool contains all of the
necessary logic to reference these new AQ commands. The end user
experience remains the same, they are using the NVMUpdate tool to
update the NVM contents.

A refactor of the i40e_vc_config_promiscuous_mode_msg function moved
the check for un-trusted VF into another function. We have to lie to
an un-trusted VF that its request to set promiscuous mode is
successful even when it is not because we don't want the VF to find
out its trust status this way. With the refactor, we were running into
a case where even though we were not setting promiscuous mode for an
un-trusted VF, we still printed a misleading message that it was
successful.
This patch fixes that by ensuring that a success message is printed
on the host side only when the promiscuous mode change has been
successful.

The function i40e_validate_cloud_filter checks that the destination and
source port numbers are valid by attempting to ensure that the number is
non-zero and no larger than 0xFFFF. However, the types for the dst_port
and src_port variable are __be16 which by definition cannot be larger
than 0xFFFF
Since these values cannot be larger than 2 bytes, the check to see if
they exceed 0xFFFF is meaningless.
One might consider these checks as some sort of defensive coding, in
case the type was later changed. However, these checks also byte-swap
the value before comparison using be16_to_cpu, which will truncate the
values to 16bits anyways. Additionally, changing the type would require
updating the opcodes to support new data layout of these virtchnl
commands.
Remove the check to silence the -Wtype-limits warning that was added to
GCC 8.

This structure was used intensively for machine specific values
when DT was not used. Since the removal of AVR32 from the kernel,
this structure is only used for passing clocks from PCI macb wrapper, all
other fields being 0.
All other known platforms use DT.
Remove the leftovers but make sure that PCI macb still works as
expected by using default values:
- phydev->irq is set to PHY_POLL by mdiobus_alloc()
- mii_bus->phy_mask is cleared while allocating it
- bp->phy_interface is set to PHY_INTERFACE_MODE_MII if mode not found

When the state of rep was introduced, it was also designed to prevent
duplicate unloading of the same rep. Considering the following two
flows when an eswitch manager is at switchdev mode with n VF reps loaded.
+--------------------------------------+--------------------------------+
| cpu-0 | cpu-1 |
| -------- | -------- |
| mlx5_ib_remove | mlx5_eswitch_disable_sriov |
| mlx5_ib_unregister_vport_reps | esw_offloads_cleanup |
| mlx5_eswitch_unregister_vport_reps | esw_offloads_unload_all_reps |
| __unload_reps_all_vport | __unload_reps_all_vport |
+--------------------------------------+--------------------------------+
These two flows will try to unload the same rep. Per original design,
once one flow unloads the rep, the state moves to REGISTERED. The 2nd
flow will no longer needs to do the unload and bails out. However, as
read and write of the state is not atomic, when 1st flow is doing the
unload, the state is still LOADED, 2nd flow is able to do the same
unload action. Kernel crash will happen.
To solve this, driver should do atomic test-and-set for the state. So
that only one flow can change the rep state from LOADED to REGISTERED,
and proceed to do the actual unloading.
Since the state is changing to atomic type, all other read/write should
be atomic action as well.

The check of legal vport is to ensure the vport number falls between
0 and total number of vports. Along with the introduction of uplink
rep, enabled vports are not consecutive any more.
Therefore, rely on the eswitch vport getter function to check if it's
a valid vport.
As the getter function relies on eswitch, add the check of vport
group manager and validation the presence of eswitch structure.
Remove the redundant check in the function calls.
Since the vport array will be allocated once eswitch is initialized
and will be kept alive if eswitch presents, no need to protect it with
the state lock.

This commit introduces support for the "Drop" action in classification
offload. This corresponds to the "-1" action with ethtool -N.
This is achieved using the color marking actions available in the C2
engine, which associate a color to a packet. These colors can be either
Green, Yellow or Red, Red meaning that the packet should be dropped.
Green and Yellow colors are interpreted by the Policer, which isn't
supported yet.
This method of dropping using the Classifier is different than the
already existing early-drop features, such as VLAN filtering and MAC
UC/MC filtering, which are performed during the Parsing step, and
therefore take precedence over classification actions.

This commit introduces basic classification offloading support for the
PPv2 controller.
The PPv2 classifier has many classification engines, for now we only use
the C2 TCAM match engine.
This engine allows to perform ternary lookups on 64 bits keys (called
Header Extracted Key), that are built by extracting fields from the packet
header and concatenating them. At most 4 fields can be extracted for a
single lookup.
This basic implementation allows to build the HEK from the following
fields :
- L4 source and destination ports (for UDP and TCP)
More fields are to be added in the future.
Classification flows are added through the ethtool interface, using the
newly introduced flow_rule infrastructure as an internal rule
representation, allowing to more easily implement tc flower rules if
need be.
The internal design for now allocates one range of 4 rules per port
due to the internal design of the flow table, which uses 22 sub-flows.
When inserting a classification rule, the rule is created in every
relevant sub-flow.
This low rule-count is a very simple design which reaches quickly the
limitations of the flow table ordering, but guarantees that the rule
ordering will always be respected.
This commit only introduces support for the "steer to rxq" action.

We don't want to use the ethtool flow definitions such as TCP_V4_FLOW,
for several reason :
- We want to decorrelate the driver code from ethtool as much as
possible, so that we can easily use other interfaces such as tc flower,
- We want the flow_type to be a bitfield, so that we can match flows
embedded into each other, such as TCP4 which is a subset of IP4.
This commit does the conversion to the newer type.

Indirect register access goes through a DCR bus bridge, which
allows only one outstanding transaction. And to make matters
worse, each TEMAC IP block contains two Ethernet interfaces, and
although they seem to have separate registers for indirect access,
they actually share the registers. Or to be more specific, MSW, LSW
and CTL registers are physically shared between Ethernet interfaces
in same TEMAC IP, with RDY register being (almost) specificic to
the Ethernet interface. The 0x10000 bit in RDY reflects combined
bus ready state though.
So we need to take care to synchronize not only within a single
device, but also between devices in same TEMAC IP.
This commit allows to do that with legacy platform devices.
For OF devices, the xlnx,compound parent of the temac node should be
used to find siblings, and setup a shared indirect_mutex between them.
I will leave this work to somebody else, as I don't have hardware to
test that. No regression is introduced by that, as before this commit
using two Ethernet interfaces in same TEMAC block is simply broken.

When in switchdev mode, we would like to treat loopback RoCE
traffic (on eswitch manager) as RDMA and not as regular
Ethernet traffic
In order to enable it we add flow steering rule that forward RoCE
loopback traffic to the HW RoCE filter (by adding allow rule).
In addition we add RoCE address in GID index 0, which will be
set in the RoCE loopback packet.

pull-request: bpf-next 2019-04-28
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Introduce BPF socket local storage map so that BPF programs can store
private data they associate with a socket (instead of e.g. separate hash
table), from Martin.
2) Add support for bpftool to dump BTF types. This is done through a new
`bpftool btf dump` sub-command, from Andrii.
3) Enable BPF-based flow dissector for skb-less eth_get_headlen() calls which
was currently not supported since skb was used to lookup netns, from Stanislav.
4) Add an opt-in interface for tracepoints to expose a writable context
for attached BPF programs, used here for NBD sockets, from Matt.
5) BPF xadd related arm64 JIT fixes and scalability improvements, from Daniel.
6) Change the skb->protocol for bpf_skb_adjust_room() helper in order to
support tunnels such as sit. Add selftests as well, from Willem.
7) Various smaller misc fixes.

The ibmvnic driver currently uses the same fixed name when using

identification along with an id for each queue.
The original idea was to use the interface name as an identifier, but it
is not feasible given these requests happen at adapter probe, and at this
point netdev is not yet registered so it doesn't have the proper name
assigned to it.

The Davinci MDIO in most of the case implemented as module inside of TI
CPSW subsystem and fully depends on CPSW to be enabled, but historically
it's implemented as separate Platform device/driver and defined in DT files
in two ways:
- as standalone node
- as child node of CPSW subsystem.
In later case it's required to split CPSW subsystem "reg" property to
exclude MDIO I/O range which is not useful.
Hence, replace devm_ioremap_resource() with devm_ioremap() to allow define

hns3_clean_tx_ring calls hns3_nic_reclaim_one_desc to clean
buffers and set ring->next_to_clean, then hns3_nic_net_xmit
reuses the cleaned buffers. But there are no memory barriers
when buffers gets recycled, so the recycled buffers can be
corrupted.
This patch uses smp_store_release to update ring->next_to_clean
and smp_load_acquire to read ring->next_to_clean to properly
hand off buffers from hns3_clean_tx_ring to hns3_nic_net_xmit.

This matches all ES versions of the affected SoCs as it is
not clear if this problem will be resolved in newer chips.
This can be revisited, as necessary.
This patch does not error-out if PHY_INTERFACE_MODE_RGMII_ID or
PHY_INTERFACE_MODE_RGMII_TXID are used on SoCs where TX clock delay

mlx5e_mpwqe_get_log_rq_size calculates the number of WQEs (N) based on
the requested number of frames in the RQ (F) and the number of packets
per WQE (P). It ensures that N is not less than the minimum number of
WQEs in an RQ (N_min). Arithmetically, it means that F / P >= N_min
should be true. This function deals with logarithms, so it should check
that log(F) - log(P) >= log(N_min). However, if F < P, this expression
will cause an unsigned underflow. Check log(F) >= log(P) + log(N_min)
instead.

This is added to better utilize the HW resources (which now makes
one less packet data prefetch) and allow better scalability, on the
account of CPU usage (which now 'memcpy's the packet into the WQE).
To load balance between HW and CPU and get max packet rate, we use
watermarks to detect how much the HW is congested and move the work
loads back and forth between HW and CPU.

The buffers mapping of the Multi-Packet WQEs (of Striding RQ)
is done via UMR posts, one UMR WQE per an RX MPWQE.
A single MPWQE is capable of serving many incoming packets,
usually larger than the budget of a single napi cycle.
Hence, posting a single UMR WQE per napi cycle (and handling its
completion in the next cycle) works fine in many common cases,
but not always.
When an XDP program is loaded, every MPWQE is capable of serving less
packets, to satisfy the packet-per-page requirement.
Thus, for the same number of packets more MPWQEs (and UMR posts)
are needed (twice as much for the default MTU), giving less latency
room for the UMR completions.
In this patch, we add support for multiple outstanding UMR posts,
to allow faster gap closure between consuming MPWQEs and reposting
them back into the WQ.
For better SW and HW locality, we combine the UMR posts in bulks of
(at least) two.
This is expected to improve packet rate in high CPU scale.
Performance test:
As expected, huge improvement in large-scale (48 cores).

This moves the IXP4xx Queue Manager and Network Processing
Engine headers out of the <mack/*> include path as that is
incompatible with multiplatform.

This adds a minimal support for booting IXP4xx systems
from device tree.
We have to add hacks to the QMGR, NPE and notably also
ethernet and watchdog drivers so that they don't crash
the platform: these drivers are unconditionally starting
to grab regions of statically remapped IO space with no
concern of the device model or other platforms.
We will go in and properly fix these drivers as we go
along but for now this hack gets us to a place where we
can start working on proper device tree support for these
platforms.

Switch the CPU port to use the new dedicated egress pool instead the
previously used egress pool which was shared with normal front panel
ports.
Add per-port quotas for the amount of traffic that can be buffered for
the CPU port and also adjust the per-{port, TC} quotas.

The CPU port is used to transmit traffic that is trapped to the host
CPU. It is therefore irrelevant to define ingress quota for it.
Add a 'skip_ingress' argument to the function tasked with configuring
per-port quotas, so that ingress quotas could be skipped in case the
passed local port is the CPU port.

The function is used to set the per-port shared buffer quotas.
Currently, these quotas are only set for front panel ports, but a
subsequent patch will configure these quotas for the CPU port as well.
The configuration required for the CPU port is a bit different than that
of the front panel ports, so split the business logic into a separate
function which will be called with different parameters for the CPU
port.
No functional changes intended.

Use the new ingress pool that was added in the previous patch for
control packets (e.g., STP, LACP) that are trapped to the CPU.
The previous management pool is no longer necessary and therefore its
size is set to 0.
The maximum quota for traffic towards the CPU is increased to 50% of the
free space in the new ingress pool and therefore the reserved space is
reduced by half, to 10KB - in both the shared and headroom buffer. This
allows for more efficient utilization of the shared buffer as reserved
space cannot be used for other purposes.

Packets that are trapped to the CPU are transmitted through the CPU port
to the attached host. The CPU port is therefore like any other port and
needs to have shared buffer configuration.
The maximum quotas configured for the CPU are provided using dynamic
threshold and cannot be changed by the user. In order to make sure that
these thresholds are always valid, the configuration of the threshold
type of these pools is forbidden.

The code currently assumes that ingress pools have lower indices than
egress pools. This makes it impossible to add more ingress pools
without breaking user configuration that relies on a certain pool index
to correspond to an egress pool.
Remove such assumptions from the code, so that more ingress pools could
be added by subsequent patches.

Multicast packets have three egress quotas:
* Per egress port
* Per egress port and traffic class
* Per switch priority
The limits on the switch priority are not exposed to the user and
specified as dynamic threshold on the first egress pool.
Forbid changing the threshold type of the first egress pool so that
these limits are always valid.
