    Hello!

    rmem_max == 65535 by default.

    Taking into account 16 bytes of mac header and 4+alignment
    for skb refcnt socket with default rmem_max can receive
    only 65476 byte frames.

    So that, to play with such frames or with IPv6 jumbograms
    rcvbuf must be increased. By user/admin, rather than by default, certainly.
