From: Alex Estrin Date: Wed, 2 May 2018 13:42:36 +0000 (-0700) Subject: IB/hfi1: Complete check for locally terminated smp X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=959f2d172daa0133e4d5b7a64344f8b2c2d87fc1;p=openwrt%2Fstaging%2Fblogic.git IB/hfi1: Complete check for locally terminated smp For lid routed packets 'hop_cnt' is zero, therefore current test is incomplete. Fix it by using local mad check for both lid routed and direct routed MADs.
