net/mlx4_en: Use __force to fix a sparse warning in TX datapath
In TX data-path, we intentionally do not byte-swap, as documented in code and in the cited commit log. This fixes sparse warning: en_tx.c:720:23: warning: incorrect type in argument 1 (different base types) en_tx.c:720:23: expected unsigned int [unsigned] [usertype] <noident> en_tx.c:720:23: got restricted __be32 [usertype] doorbell_qpn Fixes: 492f5add4be8 ("net/mlx4_en: Doorbell is byteswapped in Little Endian archs") Signed-off-by: Tariq Toukan <tariqt@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
