modifications to match 5.15. Additional, 5.15 doesn't have 504148fedb85: "net: 
add skb_[inner_]tcp_all_headers helpers", so previous arithmetic had to be 
re-implemented. There were a couple of other places where previous functions 
were maintained rather than bringing in unknown context from the commit.
  * Most changes were to MANA related source code, so leaning heavily on 
Microsoft to test there, but it is localized. MANA changes could lead to 
network instability.
  * Other changes to scsi and hyperv were small and clean cherry-picks from 
upstream, so expect little regression risk there.
