Worse than having the mac changed, all macs of all adapters are the same
now (I have multiple on the same machine).
- name changed from device-specific name to generic name
- mac changed to random one
- multiple cards now have the same mac
- the random mac change every reboot
Before they were:
3: enx8cae4cfda44c: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
link/ether 8c:ae:4c:fd:a4:4c brd ff:ff:ff:ff:ff:ff
4: enx8cae4cfda61b: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode
DEFAULT group default qlen 1000
link/ether 8c:ae:4c:fd:a6:1b brd ff:ff:ff:ff:ff:ff
and now they are:
3: eth0: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT
group default qlen 1000
link/ether e6:18:3b:a5:22:21 brd ff:ff:ff:ff:ff:ff
4: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT
group default qlen 1000
link/ether e6:18:3b:a5:22:21 brd ff:ff:ff:ff:ff:ff
The devices are:

Bus 003 Device 002: ID 0b95:1790 ASIX Electronics Corp. AX88179 Gigabit Ethernet

Title:
Incorrect MAC address on ax88179_178a USB Ethernet adapter
Status in linux-hwe-6.5 package in Ubuntu:
Confirmed
Bug description:
Starting with linux-image-6.5.0-41-generic, my AX88179 Ethernet
adapter (ax88179_178a driver) changed its MAC address to a completely
different one that has the "locally administered" bit set.
I believe this is caused by this backport:
