I have 6.3 kernel compiled with option XHCI_debug and axen2.diff implemented.
I'm using lladdr option for /etc/hostname.axen0 to have the same IP addr each session for different Ehternet adapters. Here is debug output when axen is connected: xhci0: port=2 change=0x04 xhci0: port=2 change=0x04 xhci0: xhci_cmd_slot_control xhci0: dev 1, input=0xffffff0001988000 slot=0xffffff0001988020 ep0=0xffffff0001988040 xhci0: dev 1, setting DCBAA to 0x0000000001989000 xhci_pipe_init: pipe=0xffff800000a8d000 addr=0 depth=1 port=2 speed=4 dev 1 dci 1 (epAddr=0x0) xhci0: xhci_cmd_set_address BSR=1 xhci0: xhci_cmd_set_address BSR=0 xhci0: dev 1 addr 1 axen0 at uhub0 port 2 configuration 1 interface 0 "ASIX Elec.
