From 815d456ef21a132b60ce67908d289235e9bb896c Mon Sep 17 00:00:00 2001 From: Parav Pandit Date: Tue, 19 Jun 2018 10:59:18 +0300 Subject: [PATCH] IB/cm: Pass the sgid_attr through various events Make the sgid_attr available along with path information to the event consumer, this allows the consumer to keep using the same GID table entry as the event is related to.
