Set protocol to a valid ETH_P_* protocol number you want or "all" to match all protocols. The generic offset definitions u(8|16|32) are not dependant on any protocol. u8 at 0 points to the first octet at the first payload header which some people call layer 3. u16 at 2 would be a 16bit chunk starting at the 3rd octet and so on. u8 at nexthdr+0 is the first octet at the next-header layer which some people call layer 4. You can theortically get to lower layers by specifying negative offsets. _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
