From: Norbert Ciosek <norbertx.cio...@intel.com>
[ Upstream commit 22f8b5df881e9f1302514bbbbbb8649c2051de55 ]
Remove padding from RSS structures. Previous layout
could lead to unwanted compiler optimizations
in loops when iterating over key and lut arrays.
Fixes: 65ece6de0114 ("virtchnl: Add missing explicit padding to structures")
