Title:
Fix NIC name changes for ice
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Noble:
Fix Released
Bug description:
[Impact]
This upstream commit introduced that Intel ice driver exports
"phys_port_name" in sysfs interface:
37165e3f5664 ice: introduce VF port representor
And “phys_port_name” is used by systemd when renaming NIC,
so when upgrading kernel from 5.15 to 6.8, this causes NIC name changes from
ens2f0:
kernel: ice 0000:2a:00.0 ens2f0: renamed from eth0
to ens2f0np0:
kernel: [ 21.217165] ice 0000:2a:00.0 ens2f0np0: renamed from eth0
In some circumstances, bond won't work after upgrading kernel because
of its underlying NIC name changed
[Fix]
Later, upstream removed exporting "phys_port_name" in sysfs interface in this
commit:
41355365d252 ice: Remove ndo_get_phys_port_name
It's removed in 6.10:
git tag --contains 41355365d252
v6.10
Because phys_port_name is never used, mentioned in the commit message:
ndo_get_phys_port_name is never actually used, as in switchdev
devlink is always being created.
We should make it consistent to not having "npX" in the tail of NIC
name
[ Test ]
Install 5.15 and 6.8 kernels on a machine with Intel ice NIC and see
if NIC name is the same.
[ Where the problems could occur ]
Since the "phys_port_name" is never actually used, it's find to remove
it.
