Hello José,

I'm testing on the 6.6 kernel with a "0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet" device. after applying commit 56f78615bcb1 ("net: usb: ax88179_178a: avoid writing the mac address before first reading") the network will no longer work after brining the device down.

After plugging in the device, it generally will work with ifconfig: $ ifconfig eth0 <ip address> However, if I then try bringing the devcie down and back up, it no longer works. $ ifconfig eth0 down $ ifconfig eth0 <ip address> $ ethtool eth0 | grep detected Link detected: no

The link will continue to report as undetected.

If I revert 56f78615bcb1 the device will work after bringing it down and back up.

If I build at commit d7a319889498 ("net: usb: ax88179_178a: avoid two consecutive device resets") and its parent d7a319889498^ these also work.

Is this something you have seen before with your test devices?

Regards, Jeff
