virtchnl: Fix layout of RSS structures
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") Signed-off-by: Norbert Ciosek <norbertx.ciosek@intel.com> Tested-by: Konrad Jankowski <konrad0.jankowski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
