Sorry, I should've clarified that. "Used to work" is supposed to say
"the device used the generic cdc_ether driver", as in
[ +0.000004] usb 4-1.1: Product: Lenovo Powered Hub
[ +0.000003] usb 4-1.1: Manufacturer: Lenovo
[ +0.000002] usb 4-1.1: SerialNumber: xxxxxxxxx
[ +0.024803] cdc_ether 4-1.1:2.0 eth0: register 'cdc_ether' at
usb-0000:2f:00.0-1.1, CDC Ethernet Device,
xx:xx:xx:xx:xx:xx
I guess it did technically work correctly, except for the reported issue
when the host system suspends, which is fixed by using the dedicated
Realtek driver. As far as I know this hasn't been fixed before, so it's
not a regression.
Should I update the commit message accordingly? Thanks!
Leon
