Can you please test attached patch.
And may be add some prints to the ax88772_hw_reset() and ax88772a_hw_reset().
It would be interesting to know, which variant is actually affected.
It works! Looks like it goes through ax88772_hw_reset() here. I added on
top of your patch "netdev_dbg(dev->net, "%s\n", __func__);" to beginning
of both x88772_hw_reset() and ax88772a_hw_reset().
I attached the "dmesg | grep -i asix". This time no ifconfig down/up
jump since machine got the link up and IP from the DHCP server.
You may add
