Subject: [net-next v2 10/15] i40e/i40evf: clean up error messages
From: Mitch Williams <mitch.a.williams@...el.com>
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.
