Hello! > into af_packet. What do you think? Well, comparing to copy it is good. But considering the path, which does not make transformation as the only one which requires real care about performance it is bad. New field, new initialization, new copies. Actually, I would prefer to announce that PK_PACKET,SOCK_RAW is not legal to receive such frames, to make these packets invisible for these sockets, to delete memmoves and to forget about the problem.
