First check who wrote/rewrote PF_PACKET (and a very big part of the rest of the LL/DL code) in 2.1. Then SO_ATTACH_FILTER/ SO_DETACH_FILTER are generic socket options that are handled by core/sock.c for all socket types, the receiving filter is in include/net/sock.h (that is what I missed in my first mail).
