Subject: [PATCH opensm] osm_sa_mcmember_record.c: Fix incorrect comparison of IPv6 MGID when searching for SNM MLID
Date: Tue, 01 Oct 2013 08:46:24 -0400	[thread overview]
Message-ID: <524AC420.1040602@dev.mellanox.co.il> (raw)

From: Alex Netes <alexne-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

The whole MGID except of the last 3 bytes should be compared.
