#641: Multiple nested VLAN tags don't work

 If traffic is seen with two vlan tags, Bro is currently failing.  The
 assumption in the code now is that if there is a vlan tag after the
 ethernet header there is a single vlan header and then IP is within that.
 We need to be checking the "type" field of the vlan tag to see what is
 contained within it and pass it back to the input again after stripping
 that header.
