Subject: iavf: rename functions and structs to new name
Patch-mainline: v4.20-rc1
Git-commit: 129cf89e585676ea4cc4c096bad46ad73c46e21f
References: bsc#1118658 FATE#326705
This basically begins the internal portion of the rename of i40evf to iavf,
by renaming many of the functions, structs, variables and defines.
Most of the changes were made mechanically, which introduces some
alignment issues.
