Add an "ip.h" header, to declare the IP stuff needed by dissectors, and
[tcpdump] / print-rx.c
1 /*
2 * This code unmangles RX packets. RX is the mutant form of RPC that AFS
3 * uses to communicate between clients and servers.
4 *
5 * In this code, I mainly concern myself with decoding the AFS calls, not
6 * with the guts of RX, per se.
7 *
8 * Bah. If I never look at rx_packet.h again, it will be too soon.
