af_packet: allow packets defragmentation not only for hash fanout type
Packets defragmentation was introduced for PACKET_FANOUT_HASH only, see 7736d33f4262 ("packet: Add pre-defragmentation support for ipv4 fanouts") It may be useful to have defragmentation enabled regardless of fanout type. Without that, the AF_PACKET user may have to: 1. Collect fragments from different rings 2. Defragment by itself Signed-off-by: Alexander Drozdov <al.drozdov@gmail.com> Signed-off-by: David S.
