From 13c60b99055a9e53543b7df7e4cb7eda3d6e5700 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Sat, 28 Sep 2013 07:13:18 +0000 Subject: [PATCH] i40e: assign correct vector to VF Correct math error when assigning MSI-X vectors to VFs. The vectors-per-vf value reported by the hardware already conveniently reports one less than the actual value.
