From dd6c6a5a2e1e7be615c81ca6d44c2e89e22cb463 Mon Sep 17 00:00:00 2001 From: "Michael J. Ruhl" Date: Wed, 28 Nov 2018 10:19:25 -0800 Subject: IB/hfi1: Limit VNIC use of SDMA engines to the available count VNIC assumes that all SDMA engines have been configured for use. This is not necessarily true (i.e. if the count was constrained by the module parameter). Update VNICs usage to use the configured count, rather than the hardware count.
