Bug description:
[Impact]
Microsoft has requested us to backport the following bugfix, currently
in the netdev tree:
8af174ea863c net: mana: Fix race of mana_hwc_post_rx_wqe and new hwc response
https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=8af174ea863c72f25ce31cee3baad8a301c0cf0f
[Fix]
Clean cherry-pick from the netdev tree to the
{oracular,noble,jammy}:linux-azure trees.
[Test plan]
Build and boot tested.
[Where problems could occur]
This seems to have a low risk of regression, since it's just making
sure to finish posting an RX workqueue event before waiting for
completion in order to avoid a race condition with the hardware.
However, any regressions here would likely impact users as MANA-
related errors/timeouts.
