[SRU][R:linux-azure][PATCH 0/1] [MANA] net: mana: Cache MANA_QUERY_LINK_CONFIG result to avoid repeated HWC queries

[John Cabaj]

BugLink: https://bugs.launchpad.net/bugs/2168373

SRU Justification

[Impact]

* Microsoft requested backport of patch to cache relevant MANA config information rather than performing more expensive calls to query the hardware directly.

[Fix]

* Clean cherry-pick of 8e0ffcc926f4: "net: mana: Cache MANA_QUERY_LINK_CONFIG result to avoid repeated HWC queries"

[Test Plan]

* Compile tested
* Microsoft to test further

[Regression potential]

* Patches isolated to MANA specifically. Possibly regression could result in unexpected behavior of MANA driver.

[Other info]

* SF#00441033
