There are mis-match at counting inflight IO after changing the multipath
policy.

For example, we started fio test with round-robin policy and then we
changed the policy to min-inflight. IOs created under the RR policy is
finished under the min-inflight policy and inflight counter only
decreased. So the counter would be negative value.  And also we started
fio test with min-inflight policy and changed the policy to the
round-robin. IOs created under the min-inflight policy increased the
inflight IO counter but the inflight IO counter was not decreased because
the policy was the round-robin when IO was finished.

So it should count IOs only if the IO is created under the min-inflight
policy. It should not care the policy when the IO is finished.

This patch adds a field mp_policy in struct rtrs_clt_io_req and stores the
multipath policy when an object of rtrs_clt_io_req is created. Then
rtrs-clt checks the mp_policy of only struct rtrs_clt_io_req instead of
the struct rtrs_clt.

If both eswitches are in switchdev mode and the uplink representors
are enslaved to the same bond device create a shared FDB configuration.

When moving to shared FDB mode not only the hardware needs be configured
but the RDMA driver needs to reconfigure itself.

When such change is done, unload the RDMA devices, configure the hardware
and load the RDMA representors.

When destroying the lag (can happen if a PCI function is unbinded,
driver is unloaded or by just removing a netdev from the bond) make sure
to restore the system to the previous state only if possible.

For example, if a PCI function is unbinded there is no need to load the
representors as the device is going away.

Shared FDB allows to direct traffic from all the vports in the HCA to a
single eswitch. In order to do that three things are needed.

1) Point the ingress ACL of the slave uplink to that of the master.
   With this, wire traffic from both uplinks will reach the same eswitch
   with the same metadata where a single steering rule can catch traffic
   from both ports.

2) Set the FDB root flow table of the slave's eswitch to that of the
   master. As this flow table can change dynamically make sure to
   sync it on any set root flow table FDB command.
   This will make sure traffic from SFs, VFs, ECPFs and PFs reach the
   master eswitch.

3) Split wire traffic at the eswitch manager egress ACL so that it's
   directed to the native eswitch manager. We only treat wire traffic
   from both ports the same at the eswitch level. If such traffic wasn't
   handled in the eswitch it needs to reach the right representor to be
   processed by software. For example LACP packets should *always*
   reach the right uplink representor for correct operation.

If a netdev is removed from the lag the lag should be destroyed.
With downstream patches this might trigger a reconfiguration of
representors on a different eswitch and such we don't have the proper
locking to so from this path. Move the destruction to be done by the
workqueue.

As the destruction won't affect the netdev side it okay to do so.
The RDMA side will be reconfigured and it already coded to handle such

Currently when doing hardware lag we check the eswitch mode
but as this isn't done under a lock the check isn't valid.

As the code needs to sync between two different devices an extra
care is needed.

- When going to change eswitch mode, if hardware lag is active destroy it.
- While changing eswitch modes block any hardware bond creation.
- Delay handling bonding events until there are no mode changes in
  progress.
- When attaching a new mdev to lag, block until there is no mode change
  in progress. In order for the mode change to finish the interface lock
  will have to be taken. Release the lock and sleep for 100ms to
  allow forward progress. As this is a very rare condition (can happen if
  the user unbinds and binds a PCI function while also changing eswitch
  mode of the other PCI function) it has no real world impact.

As taking multiple eswitch mode locks is now required lockdep will
complain about a possible deadlock. Register a key per eswitch to make
lockdep happy.
