Public bug reported:
[Impact]
Microsoft has requested a backport of the following bug fix to the 5.15
Azure kernels:
a43e8e9ffa0d "net: mana: Fix oversized sge0 for GSO packets"
[Fix]
Manually backport the commit, adapting changes in the
skb_[inner_]tcp_all_headers helpers due to missing commit 504148fedb85.
[Test plan]
Build/boot tested, Microsoft to do further testing.
[Where problems could occur]
This has a significant risk of regression, but the backport has been
reviewed by the author of the original commit. Any issues here would
likely manifest as hangs/timeouts coming from MANA NICs with jumbo
frames enabled.
