I need some clues about where to find information on working with mbufs. = To be more specific, I need to strip the ethernet header of a packet, do = some processing (for instance, IP=3Dmtod (m, struct ip*) should work = correctly) with it and then restore the _original_ ether header. Could someone please = give me a pointer to the information I need to get started (besides mbuf.h = and uipc_mbuf.c, which were of some help, but weren't enough) or to some = sample code? Thanks.
