 All the messages look like this:

Sep 30 13:31:11 dfw1 kernel: veth_xmit() dropped pkt reason 4:
Sep 30 13:31:11 dfw1 kernel:   src = 00:1b:d5:84:90:d2:, dst = 00:08:02:ac:36:20:
 src mac seem to belong to the stations that my dhcpd is supposed to be
serving, I don't recognize dst macs though... I'll inwestigate it if that's
important.

 To sum up - all the messages claim that drop is due to reason 4

 I don't recall if I've mentioned this, but I'm using both bridge, and
ucarp on top of the bridge.
