I don't think so.

This is not a driver issue. See: https://serverfault.com/questions/22253/ubuntu-linux-multiple-nics-same-lan-arp-responses-always-go-out-a-single-n (which has two possible solutions). (I do wonder whether having two links to the same VLAN without bonding is at all sensible, anyway.) > BTW. Is this .dtsi file responsible for GPIO configuration? All model-specific stuff is now defined by device trees. The definition for this model is spread across kirkwood-ts419-6282.dts and four other files you can see listed at the top of it. > I've also noticed a strange behavior with qcontrol: > https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=795558 So far as I can remember, device trees do not have a way to request that a GPIO should be automatically exported to userland. That will have to be done by qcontrol. Ben. -- Ben Hutchings Any sufficiently advanced bug is indistinguishable from a feature.
