I just setup a Raspberry Pi 3B+ with wrt version 22.03.5. I was able to setup a USB to wifi adapter I have and that works great but now I wanted to try and add another ethernet port.
The USB to ethernet adapter is a CISCO Linksys USB300M
and when I run lsusb I see this: ASIX Elec. Corp. AX88x72A
when I run ifconfig and IP link I don't see an eth1 even tho I have already tried installing a few drivers for it. I have kmod-usb-net-asix-ax88179 installed but still no dice.
here is my dmesg
