While at it I also get this on patch 11 (gcc-10, W=1):
drivers/net/ethernet/mellanox/mlx5/core/en_main.c: In function mlx5e_alloc_rq:
drivers/net/ethernet/mellanox/mlx5/core/en_main.c:376:6: warning: variable num_xsk_frames set but not used [-Wunused-but-set-variable]
376 | u32 num_xsk_frames = 0;
| ^~~~~~~~~~~~~~
