[Intel-wired-lan] [PATCH 09/16] ice: Expand use of VSI handles part 1/2
Anirudh Venkataramanan

Thu Sep 20 00:23:12 UTC 2018
A VSI handle is just a number the driver maintains to uniquely identify
a VSI. A VSI handle is backed by a VSI number in the hardware. When
interacting when the hardware, VSI handles are coverted into VSI numbers.
In commit 0f9d5027a749 ("ice: Refactor VSI allocation, deletion and
rebuild flow"), VSI handles were introduced but it was used only
when creating and deleting VSIs. This patch is part one of two patches
that expands the use of VSI handles across the rest of the driver. Also
in this patch, certain parts of the code had to be refactored to correctly
use VSI handles.
