Subject: [PATCH] net/mlx5: fix an uninitialized variable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit 4e66a6fef321d8015f6bde1aac5018c9ec91721c ]

Since patch "mbuf: structure reorganization" the compiler complains
sometimes (in some conditions):

 .../drivers/net/mlx5/mlx5_rxtx.c: In function ‘mlx5_rx_burst’:
 .../drivers/net/mlx5/mlx5_rxtx.c:2082:17: error: ‘len’ may be used
uninitialized in this function [-Werror=maybe-uninitialized]

len is not initialised as it will be at the first segment of a received
packet, but it remains hard for the compiler to determine it.

Fixes: 9964b965ad69 ("net/mlx5: re-add Rx scatter support")
