From 5bc160319f8a1e7ea23d7136e725f9e6a4a7628a Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Mon, 16 May 2016 10:26:43 -0700 Subject: [PATCH] i40e: set default VSI without a reset Remove the need for a reset when the device enters limited promiscuous mode. This was causing heartburn for people who were using VFs and bridging, since this would require all of the VFs to undergo a reset each time the PF changed its promiscuity.
