Maybe it should, at that? I was just a bit surprised. I've been
thinking of 802.1q trunk end points as something other than network
interfaces, but of course they're not: there's no reason why the same
physical network link shouldn't be able to carry both tagged and
...although it's probably not a good idea, most of the time. :)

That's a system wide sysctl, isn't it? Not a per interface thing?
Anyway, it doesn't make a difference, what with a trunk in practice
always being a point to point link between trunk ports on VLAN handling
Anyway, I've updated my local copy with your patch to improve the UDP
error logging, and it's running now. It'll be interesting to see what
it says -- but I guess, since my network interface does checksumming in
hardware, the reason for the error message is just that dhcpcd sees the
packet from dhcpd on the local host before it gets a checksum.
