We try to choose the lowest AC possible, to ensure the

requirements. The queue to share is chosen only from the
same RA's DATA queues as follows (in descending priority):
1. An AC_BE queue
2. Same AC queue
3. Highest AC queue that is lower than new AC
4. Any existing AC (there always is at least 1 DATA queue)

free_percpu(rt->rt6i_pcpu) used to always happen in ip6_dst_destroy().
However, after fixing a deadlock bug in
commit 9c7370a166 ("ipv6: Fix a potential deadlock when creating pcpu rt"),
free_percpu() is not called before setting non_pcpu_rt->rt6i_pcpu to NULL.
It is worth to note that rt6i_pcpu is protected by table->tb6_lock.

====================
mlxsw: Implement IPV4 unicast routing
This patchset enables IPv4 unicast routing in the Mellanox Spectrum ASIC
switch driver. This builds upon the work that was done by a couple of
previous patchsets.
Patches 1,2,6 add a couple of dependencies outside the driver. Namely, the
ability to propagate ndo_neigh_construct()/destroy() through stacked devices and
a notification whenever DELAY_PROBE_TIME changes. When propagated down, the
ndos allow drivers to add and remove neighbour entries from their private
neighbour table. The DELAY_PROBE_TIME notification gives drivers the ability to
correctly configure their polling interval for neighbour activity, so that
active neighbour won't be marked as STALE.
Patches 3-5,7-8 add the neighbour offloading infrastructure, where patch 7 uses
the DELAY_PROBE_TIME notification in order to correctly configure the device's
polling interval. Patch 8 finally programs neighbours to the device's table
based on NEIGH_UPDATE notifications, so that directly connected routes can
be used.
Patches 9-16 build upon the previous patches and extend the router with
remote routes (nexthop) support.

As previously explained, the driver should periodically poll the device
for neighbours activity according to the configured DELAY_PROBE_TIME.
This will prevent active neighbours from staying in STALE state for long
periods of time.
During init configure the polling interval according to the
DELAY_PROBE_TIME used in the default table. In addition, register a
netevent notification block, so that the interval is updated whenever
DELAY_PROBE_TIME changes.
Using the computed interval schedule a delayed work, which will update
the kernel via neigh_event_send() on any active neighbour since the last
delayed work.

When the data plane is offloaded the traffic doesn't go through the
networking stack. Therefore, after first resolving a neighbour the NUD
state machine will transition it from REACHABLE to STALE until it's
finally deleted by the garbage collector.
To prevent such situations the offloading driver should notify the NUD
state machine on any neighbours that were recently used. The driver's
polling interval should be set so that the NUD state machine can
function as if the traffic wasn't offloaded.
Currently, there are no in-tree drivers that can report confirmation for
a neighbour, but only 'used' indication. Therefore, the polling interval
should be set according to DELAY_FIRST_PROBE_TIME, as a neighbour will
transition from REACHABLE state to DELAY (instead of STALE) if "a packet
was sent within the last DELAY_FIRST_PROBE_TIME seconds" (RFC 4861).
Send a netevent whenever the DELAY_FIRST_PROBE_TIME changes - either via
netlink or sysctl - so that offloading drivers can correctly set their
polling interval.
