[SRU][N][PATCH 0/1] Fix NIC name changes for ice

[Gerald Yang]

BugLink: https://bugs.launchpad.net/bugs/2100264

[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.
