Subject: [PATCH net-next 5/9] net/mlx4: Replace mlx4_en_mac_to_u64() with mlx4_mac_to_u64()
From: Eugenia Emantayev <eugenia@...lanox.com>
Currently, the EN driver uses a private static function
mlx4_en_mac_to_u64(). Move it to a common include file (driver.h)
for mlx4_en and mlx4_ib for further use.
