[SRU][N:linux-azure-nvidia][PULL] 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]

* 6 clean cherry-picks from upstream
* 1 simple backports 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
