From: Wenzhuo Lu Date: Tue, 17 Jan 2017 08:45:07 +0000 (+0800) Subject: net/i40e: set Tx loopback from PF X-Git-Tag: spdx-start~4790 X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=bce83974ba2c;p=dpdk.git net/i40e: set Tx loopback from PF Support enabling/disabling TX loopback from PF. User can call the API on PF to enable/disable TX loopback for all the PF and VFs.
