From 3528f69637723183f997573c7ec50ca869f219ba Mon Sep 17 00:00:00 2001 From: Eli Cohen Date: Sun, 21 Apr 2013 15:10:01 +0000 Subject: [PATCH] IB/mlx4: Set link type for RAW PACKET QPs in the QP context When the link type is Ethernet, setting the link type in the QP context will enable TCP/IP stateless offloads (checksum, LSO, RSS) for RAW PACKET Ethernet QPs. For IB UD QPs this worked OK since the value assumed by the firmware for IB link layer is zero.
