[SRU][N:linux-azure/O:linux-azure/P:linux-azure][PATCH 0/7] Hyper-V and MANA enhancements

[John Cabaj]

BugLink: https://bugs.launchpad.net/bugs/2098508

SRU Justification

[Impact]

* Microsoft requested patches to implement debugfs in MANA driver to improve debugging in userspace, improve available settings in ethtool, and vmbus enhancements to fix potential hang and improve throughput

[Fix]

* Noble: 6 clean cherry-picks, 1 backport from upstream
* Oracular: 6 clean cherry-picks from upstream
* Plucky: 4 clean cherry-picks from upstream

[Test Plan]

* Compile tested
* Boot tested
* Will be further tested by Microsoft

[Regression potential]

* Changes are largely localized to MANA and hyper-v. scsi change simply initializes as variable that should have already been initialized. Most changes have been upstreamed for some months.
* Introduction of debugfs to MANA driver could introduce regressions if not well tested.

[Other info]

* SF#00406456
