a9b059643b Fix regression issue after r352989: 
As noted by the commit message, callouts are now persistant
and should not be in the auto-zero section of the RQ's and SQ's.
This fixes an assert when using the TX completion event
factor feature with mlx5en(4).

7869843218 Wait for FW readiness before initializing command interface in mlx5core. 
Before attempting to initialize the command interface we must wait till
the fw_initializing bit is clear.

If we fail to meet this condition the hardware will drop our
configuration, specifically the descriptors page address.  This scenario
can happen when the firmware is still executing an FLR flow and did not
finish yet so the driver needs to wait for that to finish.

cd0bc32f20 Seal transmit path with regards to using destroyed mutex in mlx5en(4). 
It may happen during link down that the running state may be observed
non-zero in the transmit routine, right before the running state is
cleared. This may end up using a destroyed mutex.

Make all channel mutexes and callouts persistant.

Preserve receive and send queue statistics during link toggle.

bf8cde114e Add support for Multi-Physical Function Switch, MPFS, in mlx5en. 
MPFS is a logical switch in the Mellanox device which forward packets
based on a hardware driven L2 address table, to one or more physical-
or virtual- functions. The physical- or virtual- function is required
to tell the MPFS by using the MPFS firmware commands, which unicast
MAC addresses it is requesting from the physical port's traffic.
Broadcast and multicast traffic however, is copied to all listening
physical- and virtual- functions and does not need a rule in the MPFS
switching table.
