packets (based on the Ethernet type). "pppoes" has the side-effect that

Ethernet, so, at least on Ethernet, when checking for IPX frames, check

letting you filter based on the VLAN to which a packet belongs, and an
improvement to the printing of VLAN packets (adding an extra space to
separate the VLAN priority and flags from the next stuff printed).
"linux-includes/netinet/if_ether.h" to "ethertype.h", and remove
includes of <netinet/if_ether.h> from files that only include it to get
ETHERTYPE_ values defined.
