From: John Daley Date: Wed, 12 Oct 2016 21:22:29 +0000 (-0700) Subject: net/enic: fix multi-queue Rx performance X-Git-Tag: spdx-start~5473 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=ce16fd705cdab72ee17b9f345eec1c88c6da06f6;p=dpdk.git net/enic: fix multi-queue Rx performance The rx_free_thresh was not being initialized and left at 0 on 1/2 of the RQs which could lead to poor multi-queue performance.
