ESIS dissectors. Register the IP dissector and have dissectors that call it directly (rather than through a port table) call it through a handle. Add a routine "tvb_set_reported_length()" which a dissector can use if it was handed a tvbuff that contains more data than is actually in its part of the packet - for example, handing a padded Ethernet frame to IP; the routine sets the reported length of the tvbuff (and also adjusts the actual length, as appropriate). Then use it in IP. Given that, "ethertype()" can determine how much of the Ethernet frame was actually part of an IP datagram (and can do the same for other protocols under Ethernet that use "tvb_set_reported_length()"; have it return the actual length, and have "dissect_eth()" and "dissect_vlan()" use that to mark trailer data in Ethernet II frames as well as in 802.3 frames. svn path=/trunk/; revision=2658
