I just reverted that, so you can simplify your diff.

Initialize ret to 0 for case when nothing is found

Otimized, ethno calculated in callers to avoid one for over ifnets

sys/compat/linux/linux.c
249	Nit: ‘const char *bsdname’. It would help to understand whar ‘len’ refers to

ifnet_byindex, ifuint instead of handmade,
also use net ecoch in modified code, others later

fix ifconf, btw, ifconf is no more used by glibc, replaced by netlink...

sys/compat/linux/linux.c
308	There can be more that one loopback interface, so I guess we need to rename only the first one (e.g. "lo0") and keep the rest intact.
sys/compat/linux/linux_ioctl.c
2171–2172

This revision is now accepted and ready to land.Feb 22 2023, 12:52 PM

fix lo -> lo0, loX -> loX translation
