Define the default for whatever you wish to have as the default class
for non-ip traffic and then filter _all_ ip traffic into a certain
class, eg:

  tc filter add dev $DEV parent 1: protocol ip prio 18 u32 \
     match ip dst 0.0.0.0/0 flowid 1:20

Or, even more modularily, use the MARK target at the end of your
iptables ruleset after all other markings:

  iptables -t mangle -A POST_ROUTING -m mark --mark 0 -j MARK --set-mark 3
  iptables -t mangle -A OUTPUT -m mark --mark 0 -j MARK --set-mark 3

And then just setup your tc to match the marks to classes:

  tc filter add dev $DEV parent 1: protocol ip prio 10 \
      handle 3 fw \
      flowid 1:30

Or a variety of other solutions.

I am not sure if this will solve your problem exactly, though - since
having problems with ARP traffic and so seems really odd.
