From 916c5e1413be058d1c1f6e502db350df890730ce Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Fri, 13 Jul 2018 10:38:38 -0700 Subject: [PATCH] hv/netvsc: fix handling of fallback to single queue mode The netvsc device may need to fallback to running in single queue mode if host side only wants to support single queue. Recent change for handling mtu broke this in setup logic.
