#5228, to correctly check for Appletalk for EtherTalk phase II - they
use 802.3 with LLC SNAP packets, rather than D/I/X Ethernet packets.
His patch made "atalk" check for Appletalk ARP as well as other
Appletalk packets; I've instead added a separate "aarp" packet type,
leaving "atalk" checking only for ETHERTYPE_ATALK, so you can check for
ETHERTYPE_ATALK, ETHERTYPE_AARP, or both.
counting any extra jumps required by a flowgraph node (the conditional
jump instructions have an 8-bit offset; if the target is more than 256
instructions away, we generate a nearby "jump always" to the target, and
jump to that instead).
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).
