From bdb3bf9246ff614029a41e6432fe7696e21f607f Mon Sep 17 00:00:00 2001 From: Jingjing Wu Date: Mon, 30 Nov 2015 11:54:09 +0800 Subject: [PATCH] i40evf: fix MAC deletion when stopping When dev_stop is called in i40evf pmd driver, queues are switched off to stop receiving and transmitting. But the mac address of this VF still exists in VEB switch. To stop the traffic from VSI level, the mac address need to be removed too. Then the bandwidth for this SRIOV VSI can be freed. This patch fix this issue.
