eb62cca9be qed: Fix QM getters to always return a valid pq
The getter callers doesn't know the valid Physical Queues (PQ) values.
This patch makes sure that a valid PQ will always be returned.

The patch consists of 3 fixes:

 - When qed_init_qm_get_idx_from_flags() receives a disabled flag, it
   returned PQ 0, which can potentially be another function's pq. Verify
   that flag is enabled, otherwise return default start_pq.

 - When qed_init_qm_get_idx_from_flags() receives an unknown flag, it
   returned NULL and could lead to a segmentation fault. Return default
   start_pq instead.

 - A modulo operation was added to MCOS/VFS PQ getters to make sure the
   PQ returned is in range of the required flag.

e432abfb99 net: hns3: add common validation in hclge_dcb
Before setting tm related configuration to hardware, driver
needs to check the configuration provided by user is valid.
Currently hclge_ieee_setets and hclge_setup_tc both implement
their own checking, which has a lot in common.

This patch addes hclge_dcb_common_validate to do the common
checking. The checking in hclge_tm_prio_tc_info_update
and hclge_tm_schd_info_update is unnecessary now, so change
the return type to void, which removes the need to do error
handling when one of the checking fails.

Also, ets->prio_tc is indexed by user prio and ets->tc_tsa is
indexed by tc num, so this patch changes them to use different
index.

Ido Schimmel says:

====================
selftests: Add tests for VXLAN at an 802.1d bridge

Petr says:

This patchset adds several tests for VXLAN attached to an 802.1d bridge
and fixes a related bug.

First patch #1 fixes a bug in propagating SKB already-forwarded marks
over veth to bridges, where they are irrelevant. This bug causes the
vxlan_bridge_1d test suite from this patchset to fail as the packets
aren't forwarded by br2.

In patches #2 and #3, lib.sh is extended to support network namespaces.
The use of namespaces is necessitated by VXLAN, which allows only one
VXLAN device with a given VNI per namespace. Thus to host full topology
on a single box for selftests, the "remote" endpoints need to be in
namespaces.

In patches #4-#6, lib.sh is extended in other ways to facilitate the
following patches.

In patches #7-#15, first the skeleton, and later the generic tests
themselves are added.

Patch #16 then adds another test that serves as a wrapper around the
previous one, and runs it with a non-default port number.

Patches #17 and #18 add mlxsw-specific tests. About those, Ido writes:

The first test creates various configurations with regards to the VxLAN
and bridge devices and makes sure the driver correctly forbids
unsupported configuration and permits supported ones. It also verifies
that the driver correctly sets the offload indication on FDB entries and
the local route used for VxLAN decapsulation.

The second test verifies that the driver correctly configures the singly
linked list used to flood BUM traffic and that traffic is flooded as
expected.

"local", possibly offloaded, and two "remote", formed using veth pairs
and likely purely software bridges. The "local" endpoint is connected to

Since VXLAN tunnels must be unique per namespace, each of the "remote"
endpoints is in its own namespace. H3 forms the bridge between the three
domains.

d0540d1706 selftests: forwarding: lib: Add in_ns()
In order to run a certain command inside another network namespace, it's
possible to use "ip netns exec ns command". However then one can't use
functions defined in lib.sh or a test suite.

One option is to do "ip netns exec ns bash -c command", provided that
all functions that one wishes to use (and their dependencies) are
published using "export -f". That may not be practical.

Therefore, introduce a helper in_ns(), which wraps a given command in a
boilerplate of "ip netns exec" and "source lib.sh", thus making all
library functions available. (Custom functions that a script wishes to
run within a namespace still need to be exported.)

Because quotes in "$@" aren't recognized in heredoc, hand-expand the
array in an explicit for loop, leveraging printf %q to handle proper
quoting.

Therefore replace the {1..$NUM_NETIFS} references, which cause iteration
over 1 and 0, with an explicit for loop like we do in setup_wait() and
tc_offload_check(), so that for NUM_NETIFS of 0 no iteration is done.

6f9a506910 net: skb_scrub_packet(): Scrub offload_fwd_mark
When a packet is trapped and the corresponding SKB marked as
already-forwarded, it retains this marking even after it is forwarded
across veth links into another bridge. There, since it ingresses the
bridge over veth, which doesn't have offload_fwd_mark, it triggers a
warning in nbp_switchdev_frame_mark().

Then nbp_switchdev_allowed_egress() decides not to allow egress from
this bridge through another veth, because the SKB is already marked, and
the mark (of 0) of course matches. Thus the packet is incorrectly
blocked.

Solve by resetting offload_fwd_mark() in skb_scrub_packet(). That
function is called from tunnels and also from veth, and thus catches the
cases where traffic is forwarded between bridges and transformed in a
way that invalidates the marking.

Sunil Goutham says:

====================
octeontx2-af: NPC MCAM support and FLR handling

This patchset is a continuation to earlier submitted three patch
series to add a new driver for Marvell's OcteonTX2 SOC's
Resource virtualization unit (RVU) admin function driver.

1. octeontx2-af: Add RVU Admin Function driver
   https://www.spinics.net/lists/netdev/msg528272.html
2. octeontx2-af: NPA and NIX blocks initialization
   https://www.spinics.net/lists/netdev/msg529163.html
3. octeontx2-af: NPC parser and NIX blocks initialization
   https://www.spinics.net/lists/netdev/msg530252.html

This patch series adds support for below
RVU generic:
- Function Level Reset irq handler
  When FLR is triggered for PFs, AF receives interrupt.
  This patchset adds logic for cleaning up of NPA, NIX
  and NPC block resources being used by PF.

- Mailbox communication between AF and it's VFs.
  Unlike VFs of PF1-PFn, AF which is PF0 can communicate
  with it's VFs directly. Added support for the same.

- AF's VFs IO configuration
  These VFs are mapped to use internal HW loopback channels
  instead of CGX LMACs. Each pair of VFs work as two of ends
  of hardwired interfaces. VF0's TX is VF1's Rx & viceversa.

NPC block:
- MCAM entry management
  Alloc/Free of contiguous/non-contiguous and lower/higher
  priority MCAM entry allocation and programming support.
- MCAM counters management and map/unmap with MCAM entries
- Default KEY extract profile
- HW errata workarounds

NIX block:
- Minimum and maximum allowed packet length config
- HW errata workarounds

Few more changes like shift to use mutex instead of spinlock etc
are done in this patchset.

Changes from v2:
 1 Fixed commit message of patch 'Relax resource lock into mutex'
   to a more unambiguous one.
   - Suggested by David Miller.

Changes from v1:
 1 Converted all mailbox message handler API names to small letters
   from mixed small and capital letters.
   - Suggested by David Miller.
 2 Fixed endian issues in patch 'Add support for stripping STAG/CTAG'
   - Suggested by Arnd Bergmann
 3 Elaborated commit message of patch 'Add FLR interrupt handler'
   to make it a bit more easy to understand.
   - Suggested by Arnd Bergmann

 Will fix the padding and alignment in mailbox message structure
 in a follow-up patch.

VFs attached to PFs other than AF can not communicate with AF

Responses to messages are handled in the reverse order.

On the other hand if VFs are on AF (PF0) itself then direct mailbox
communication is possible since there's no other PF in the way.

This patch addresses this particular case and adds support for

Likewise while PF/VF is being teared down, it can send the disable
mailbox message to stop receiving traffic.

631e70bb84 octeontx2-af: Add MKEX default profile
Added basic default MKEX profile. This profile tells
hardware what data to extract from packet and where to
place it (bit offset) in final KEY generated for the
parsed packet. Based on the bit placement of the packet
data, MCAM entries have to programmed for matching.

Also added a msg to retrieve this MKEX profile from PF/VF
which inturn can process it to determine how MCAM entry
has to be populated.

63be91c89d octeontx2-af: Alloc and config NPC MCAM entry at a time
A new mailbox message is added to support allocating a MCAM entry
along with a counter and configuring it in one go. This reduces
the amount of mailbox communication involved in installing a new
MCAM rule.

a958dd59f9 octeontx2-af: Map or unmap NPC MCAM entry and counter
Alloc memory to save MCAM 'entry to counter' mapping and since
multiple entries can map to same counter, added counter's reference
count tracking.

Do 'entry to counter' mapping when a entry is being installed
and mbox msg sender requested to configure a counter as well.
Mapping is removed when a entry or counter is being freed or
a explicit mbox msg is received to unmap them.

7fbb3f238c octeontx2-af: Support for NPC MCAM counters
NPC HW has counters which can be mapped to MCAM
entries to gather entry match statistics. This
patch adds support to allocate, free, clear and retrieve
stats of NPC MCAM counters. New mailbox messages have
been added for this. Similar to MCAM entries both
contiguous and non-contiguous counter allocation is
supported.

Add support for a RVU PF/VF to enable, disable, configure
and shuffle MCAM entries via mbox commands. This patch adds
mailbox message formats and handling of these commands.

As of now otherthan validating MCAM entry index, info like
channel number e.t.c in MCAM config data sent by PF/VF are
not validated.

Also a max of 64 MCAM entries can be shuffled with a single
mbox command.

if request cannot be met then max contiguous number of available
entries are allocated.

High or low priority index allocation w.r.t a reference MCAM index

0964fc8f5f octeontx2-af: Relax resource lock into mutex
Mailbox message handling is done in a workqueue context scheduled
from interrupt handler. So resource locks does not need to be a spinlock.
Therefore relax them into a mutex so that later on we may use them
in routines that might sleep.

rtl8168_oob_notify is used in rtl8168dp_driver_start and
rtl8168dp_driver_stop only, so we can rename it to r8168dp_oob_notify.
The same applies to condition rtl_ocp_read_cond which can be renamed
to rtl_dp_ocp_read_cond. This allows to simplify the code.
