Bug Description
SRU Justification
[Impact]
MSFT has requested to backport commit a7dfeda6fdeccab
When unloading the MANA driver, mana_dealloc_
hardware to complete any inflight packets and set the pending send count
to zero. But if the hardware has failed, mana_dealloc_
could wait forever.
[Test Plan]
Microsoft tested. Commit upstream since 6.5
[Regression Potential]
The MANA driver may not shut down correctly.
