From ca85bb1ca9948899682fe7170636e465599ea8e7 Mon Sep 17 00:00:00 2001 From: Sebastian Sanchez Date: Thu, 1 Feb 2018 10:46:38 -0800 Subject: IB/hfi1: Remove unnecessary fecn and becn fields packet->fecn and packet->becn are calculated in the hot path and are never used. Remove these fields as they show to be costly in a profile. Also, remove initialization for becn and fecn in process_ecn() as they're unconditionally assigned in the function and ensure fecn and becn variables use a boolean type.
