From 35f3472a750b3549f7f914ed96f41f0c2ca284f3 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Wed, 17 Feb 2016 16:12:23 -0800 Subject: [PATCH] i40e: let go of the past If we reset a VF, its VSI goes away, and it gets a new one. So don't hang on to the now-stale local VSI pointer. It just leads to suffering and kernel panics.
