** Description changed:
SRU Justification
[Impact]
Previously, the maximum queue depth supported for gVNIC on overcommitted
Gen3+ VMs
(such as N4) was increased from 1K to 4K in the GCP kernel using the patchset
titled
"Support larger gVNIC queue depth on Gen3+ GCE VMs". However, the upstream
commit
5e37d8254e7f ("gve: Add header split data path") has two additional bug-fix
commits.
This patchset targets and applies those two specific fixes.
[Fix]
Noble (6.8) and Jammy (5.15)
d676c9a73bdc ("gve: fix header buffer corruption with header-split and
HW-GRO")
6bf14575c655 ("gve: fix zero-length skb frag with header-split")
Resolute (7.0)

+ d676c9a73bdc was already received via CVE fix backport CVE-2026-72046
6bf14575c655 ("gve: fix zero-length skb frag with header-split")
[Test Plan]
* Compile Tested
* Boot Tested
- * The following output indicates the feature is missing:
- $ sudo ethtool -G enp0s0 rx 4096
- netlink error: Operation not supported
- So the test plan for Canonical was to confirm that `sudo ethtool -G enp0s0
rx
- 4096` exits successfully without an error.
- * As well as this command, it should return 4096 as max no 1024:
- ethtool -g enp0s0
[Regression potential]
Regressions should only be possible when using the gVNIC device for
networking (which depends on the gve driver), and could most likely result in
networking failures on those configurations.
