From 3f34b24a732bab9635c4b32823268c37c01b40f0 Mon Sep 17 00:00:00 2001 From: Alexander Drozdov Date: Fri, 20 Feb 2015 08:24:27 +0300 Subject: 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 Signed-off-by: David S.
