I'm not familiar Ubuntu's versioning and custom patches, nor their backport policy. However their "mantic" tree (6.5) looks like this: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/mantic/t= ree/drivers/net/ethernet/intel/igc/igc_ethtool.c#n1804 So the patch above not applied there. >=20 > > I just switched back to 6.2 and with that it works correctly. > >=20 > > Sorry if this has already been addressed, after a quick search in > > the > > lore I cannot find anything related. > >=20 >=20 > I think it was discussed here: >=20 > https://lore.kernel.org/all/20230922163804.7DDBA2440449@us122.sjc.aristan= etworks.com/ Thank you, look like I missed it.
