From b76a5b14f558eb3b5eba41dbd0c440fe69e25fe4 Mon Sep 17 00:00:00 2001 From: Doug Oucharek Date: Mon, 1 May 2017 15:29:49 -0700 Subject: [PATCH] LU-9425 lnd: Turn on 2 sges by default Currently, the fix in LU-5718 which allows for multiple sges to deal with RDMA fragmentation is turned off by deafult (set to 1). This patch changes the default to 2 so RDMA fragmentation is fixed by default.
