From 8d8f2295d0752230e0a697af33e5af96561b64a0 Mon Sep 17 00:00:00 2001 From: Mitch Williams Date: Wed, 21 Oct 2015 19:47:11 -0400 Subject: [PATCH] i40e/i40evf: clean up error messages Clean up and enhance error messages related to VF MAC/VLAN filters. Indicate which VF is having issues, and if possible indicate the MAC address or VLAN involved. Also, when an error is returned from the PF driver, print useful information about what went wrong, for the most likely cases.
