Subject: [net-next v2 11/15] ice: add helpers for virtchnl
From: Jesse Brandeburg <jesse.brandeburg@...el.com>
The virtchannel interface was repeating a lot of strings
and wasting storage space in the kernel. There was also
inconsistent messages for the same thing. Consolidate all
those messages and bit checks into a couple of helper functions.
Also, reduce stack space usage by simplifying getting the pointer
to the pf using a helper.
