Subject: Regression with commit e532a096be0e ("net: usb: asix: ax88772: add phylib support")

Message-ID: <3904c728-1ea2-9c2b-ec11-296396fd2f7e@linux.intel.com> (raw)
Hi
Our ASIX USB ethernet adapter stopped working after v5.14-rc1. It
doesn't get an IP from DHCP.
v5.13 works ok. v5.14-rc1 and today's head 761c6d7ec820 ("Merge tag
'arc-5.14-rc6' of
git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc") show the
regression.
I bisected regression into e532a096be0e ("net: usb: asix: ax88772: add
phylib support").
Here's the dmesg snippet from working and non-working cases:
OK:
