The Gemini ethernet has been around for years as an out-of-tree
patch used with the NAS boxen and routers built on StorLink
SL3512 and SL3516, later Storm Semiconductor, later Cortina
Systems. These ASICs are still being deployed and brand new
off-the-shelf systems using it can easily be acquired.
The full name of the IP block is "Net Engine and Gigabit
Ethernet MAC" commonly just called "GMAC".
The hardware block contains a common TCP Offload Enginer (TOE)
that can be used by both MACs. The current driver does not use
it.

In commit 232d07b74a ("tipc: improve groupcast scope handling") we
inadvertently broke non-group multicast transmission when changing the
parameter 'domain' to 'scope' in the function
tipc_nametbl_lookup_dst_nodes(). We missed to make the corresponding
change in the calling function, with the result that the lookup always
fails.
A closer anaysis reveals that this parameter is not needed at all.
Non-group multicast is hard coded to use CLUSTER_SCOPE, and in the
current implementation this will be delivered to all matching
destinations except those which are published with NODE_SCOPE on other
nodes. Since such publications never will be visible on the sending node
anyway, it makes no sense to discriminate by scope at all.
We now remove this parameter altogether.

Since net could be obtained from RCU lists,
and there is a race with net destruction,
the patch converts net::count to refcount_t.
This provides sanity checks for the cases of
incrementing counter of already dead net,
when maybe_get_net() has to used instead
of get_net().
Drivers: allyesconfig and allmodconfig are OK.

I see two issues with parameter new_link:
1. It's not needed. See also phy_interrupt(), works w/o this parameter.
phy_mac_interrupt sets the state to PHY_CHANGELINK and triggers the
state machine which then calls phy_read_status. And phy_read_status
updates the link state.
2. phy_mac_interrupt is used in interrupt context and getting the link
state may sleep (at least when having to access the PHY registers
via MDIO bus).
So let's remove it.

__phy_modify would return the old value of the register before it was

Thus functions using phy_modify, which is a wrapper around
__phy_modify, can start returning > 0 on success, rather than 0. As a
result, breakage has been noticed in various places, where 0 was
assumed.
Code inspection does not find any current location where the return of
the old value is currently used. So have __phy_modify return 0 on
success. When there is a real need for the old value, either a new

10GbE Intel Wired LAN Driver Updates 2018-01-12
This series contains updates to ixgbe, fm10k and net core.
Alex updates the driver to remove a duplicate MAC address check and
verifies that we have not run out of resources to configure a MAC rule
in our filter table. Also do not assume that dev->num_tc was populated
and configured with the driver, since it can be configured via mqprio
without any hardware coordination. Fixed the recording of stats for
MACVLAN in ixgbe and fm10k instead of recording the receive queue on
MACVLAN offloaded frames. When handling a MACVLAN offload, we should
be stopping/starting traffic on our own queues instead of the upper
devices transmit queues. Fixed possible race conditions with the
MACVLAN cleanup with the interface cleanup on shutdown. With the
recent fixes to ixgbe, we can cap the number of queues regardless of
accel_priv being in use or not, since the actual number of queues are
being reported via real_num_tx_queues.
Tony fixes up the kernel documentation for ixgbe and ixgbevf to resolve

mlxsw: Offload PRIO qdisc
Nogah says:
Add an offload support for PRIO qdisc for mlxsw driver.
PRIO qdisc is being offloaded by using ndo_setup_tc. It has three
commands, to set or tune the qdisc, to remove it and to get its stats.
Like RED offloading, offloading this qdisc is not enforced on the driver
and determining its offload state is done in the dump action, when the
stats are being updated.
In the driver, offloading of PRIO is supported as root qdisc only. It
supports only priorities 0-7 (the range that is used by the current static
mapping of DSCP to skb prio and by 1:1 PCP values mapping) and up to 8
bands.
Patches 1-2 offload DSCP to priority mapping in the mlxsw_sp driver.
Patch 3 adds offload support for PRIO qdisc.
Patches 4-5 Add PRIO offload support in the mlxsw_sp driver.

- Patch 3/5:

Support basic stats for PRIO qdisc, which includes tx packets and bytes
count, drops count and backlog size. The rest of the stats are irrelevant
for this qdisc offload.
Since backlog is not only incremental but reflecting momentary value, in
case of a qdisc that stops being offloaded but is not destroyed, backlog
value needs to be updated about the un-offloading.
For that reason an unoffload function is being added to the ops struct.

* TC_PRIO_DESTROY: handles qdisc destroy
* TC_PRIO_STATS: updates the qdiscs counters (given as reference)
Like RED qdisc, the indication of whether PRIO is being offloaded is being
set and updated as part of the dump function. It is so because the driver
could decide to offload or not based on the qdisc parent, which could
change without notifying the qdisc.

Now that the kernel supports weighted IPv6 nexthops, we can extend the

This is done by assigning each nexthop its configured weight, so that it
will be populated accordingly in the device's adjacency table. The

Since the TX GL and the RX GL need to be set separately,
hns3_set_vector_coalesc_gl() has been replaced with
hns3_set_vector_coalesce_rx_gl() and hns3_set_vector_coalesce_tx_gl().
This patch removes hns3_set_vector_coalesc_gl().

The GL update function uses the max GL value between tx_int_gl and
rx_int_gl to set both new tx_int_gl and new rx_int_gl. Therefore, User
can not enable TX GL self-adaptive or RX GL self-adaptive individually.
This patch refactors the code to update the TX GL and the RX GL
separately, making user can enable TX GL self-adaptive or RX GL
self-adaptive individually.

In the hardware, the coalesce configurable registers include GL0, GL1,
GL2. In the driver, the TX queues use the register GL1 and the RX queues
use the register GL0. This function initializes the configuration of the
interrupt coalescing, but does not distinguish between the TX direction
and the RX direction. It will cause some confusion.
This patch refactors the function to initialize the TX GL and the RX GL
separately. And the initialization of related variables also is added to
this patch.

This patch adds ethtool_ops.get_coalesce support to PF.
Whilst our hardware supports per queue values, external interfaces
support only a single shared value. As such we use the values for
queue 0.

BPF alignment tests got a conflict because the registers
are output as Rn_w instead of just Rn in net-next, and
in net a fixup for a testcase prohibits logical operations
on pointers before using them.
Also, we should attempt to patch BPF call args if JIT always on is
enabled. Instead, if we fail to JIT the subprogs we should pass
an error back up and fail immediately.
