From: Harish Patil Date: Wed, 28 Mar 2018 00:15:51 +0000 (-0700) Subject: net/qede: convert to new Rx/Tx offloads API X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=946dfd18a4ec;p=dpdk.git net/qede: convert to new Rx/Tx offloads API Ethdev RX/TX offloads API has changed since: commit ce17eddefc20 ("ethdev: introduce Rx queue offloads API") commit cba7f53b717d ("ethdev: introduce Tx queue offloads API") This patch makes use of new offload flags as suggested and fix the default RX/TX configuration. Also indent the code properly around those changes.
