- During debugging and testing we noticed that while
"dev_set_mac_address" used to set "addr_assign_type" to NET_ADDR_SET,
the mentioned commit directly sets "addr_assign_type" to NET_ADDR_RANDOM
and the called "eth_hw_addr_set" does not modify the type afterwards.
If I change line 874 "net->addr_assign_type = NET_ADDR_RANDOM;" to
"net->addr_assign_type = NET_ADDR_SET;" then the issue seems to be solved.
- Regarding bootargs and defconfig, we encountered the issue with our
custom board and some own/modified drivers and additional patches, which
might make it difficult to reproduce the issue outside of our setup.

[1.] One line summary of the problem:
No static MAC address for usb gadget ethernet via kernel boot parameter any more.
[2.] Full description of the problem/report:
In 5.15. and before we were able to set a static MAC address for the usb gadget ethernet connection using kernel parameters "g_ether.dev_addr" and "g_ether.host_addr".
Since 5.16. and more concrete after commit 890d5b40908bfd1a79be018d2d297cf9df60f4ee, this is no longer possible, and a random MAC address is assigned.
