SRU Justification:
[Impact]
* Since older firmware may not support the uplink state setting, this can lead to problems.
* Now expose firmware indication that it supports setting eswitch uplink state to follow the physical link.
* <... some more details are needed on how things fail today, w/o the patch>
[Fix]
* upstream fix (as in 5.11):

* backport for groovy:

[Test Case]
* It requires an IBM Z or LinuxONE system, with groovy/focal installed in LPAR
and RoCE Express 2.x adapters attached.
* Due to the lack of hardware this needs to be verifid by IBM.
[Regression Potential]
* This backport fixes a regression which was introduced with the kernel 5.4.0-48 update for Ubuntu 20.04.
[Other]
* The above patch/commit was upstream accepted with kernel 5.11.
* Hence the patch is not needed for hirsute, just SRUs for groovy and focal are needed.
* But the commit couldn't be cleanly cherry-picked, due to changed context, hence the backport(s).
