From 4e66a6fef321d8015f6bde1aac5018c9ec91721c Mon Sep 17 00:00:00 2001 From: Nelio Laranjeiro Date: Thu, 6 Apr 2017 11:16:32 +0200 Subject: [PATCH] net/mlx5: fix an uninitialized variable MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
