Public bug reported:
SRU Justification
[Impact]
MSFT has requested to backport commit
a7dfeda6fdeccab4c7c3dce9a72c4262b9530c80 ('net: mana: Fix MANA VF unload
when hardware is unresponsive').
When unloading the MANA driver, mana_dealloc_queues() waits for the MANA
hardware to complete any inflight packets and set the pending send count
to zero. But if the hardware has failed, mana_dealloc_queues()
could wait forever.
[Test Plan]
Microsoft tested. Commit upstream since 6.5
[Regression Potential]
The MANA driver may not shut down correctly.
