From ff8b67fccdb65402df78a1695c38be805252cf8e Mon Sep 17 00:00:00 2001 From: Ashutosh Dixit Date: Wed, 28 Nov 2018 10:19:47 -0800 Subject: [PATCH] IB/hfi1: Consider LMC in 16B/bypass ingress packet check Ingress packet check for 16B/bypass packets should consider the port LMC. Not doing this will result in packets sent to the LMC LIDs getting dropped. The check is implemented in HW for 9B packets.
