From 97f1e196799f5664a2f677f789fbe06e1d5ab87a Mon Sep 17 00:00:00 2001 From: Wei Dai Date: Sun, 23 Jul 2017 17:15:12 +0800 Subject: [PATCH] app/testpmd: add port reset command When PF is reset, a message will show it and all its VF need to be reset. User can run the command "port reset port_id" to reset the VF port and to keep same port id without any configuration. Then user can run "port stop port_id" and "port start port_id" to reconfigure its forwarding mode and parameters as previous ones. To avoid crash, current forwarding should be stopped before running "port reset port_id".
