From: Rasesh Mody Date: Tue, 22 May 2018 23:16:03 +0000 (-0700) Subject: net/qede: fix VF MTU update X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=d121a6b5f781;p=dpdk.git net/qede: fix VF MTU update This patch fixes VF MTU update to work without having to restart the vport and there by not requiring port re-configuration. It adds a VF MTU Update TLV to achieve the same. Firmware can handle VF MTU update by just pausing the vport.
