Subject: [next-queue 6/7] ixgbevf: Fix code comments and whitespace
Fix the code comments to align with drivers/net/ code commenting style,
as well as whitespace issues. The whitespace issues resolve checkpatch
errors, like lines exceeding 80 chars (except for strings) and the use
of tabs where possible.
