From 802f42a8d99254b8602bf65cc50e8333bf479f13 Mon Sep 17 00:00:00 2001 From: Ido Shamay Date: Thu, 2 Apr 2015 16:31:06 +0300 Subject: net/mlx4: Add RSS support for fragmented IP datagrams Enable RSS support for fragmented IP packets, when device supports it. Until now, fragmented IP packets were directed only to the default_qpn. Since IP fragments (datagram) have no upper protocols (L3 IP packets), hash is performed on 3-tuple - dst MAC, source IP and dest IP. The HW makes sure that this holds for the 1st fragment too, so all fragments go to the same QP. Signed-off-by: Ido Shamay Signed-off-by: Or Gerlitz Signed-off-by: David S.
