Subject: [PATCH net] net/mlx5e: Fix del vxlan port command
Date: Wed, 20 Jul 2016 17:48:48 +0300	[thread overview]
Message-ID: <1469026128-15975-1-git-send-email-saeedm@mellanox.com> (raw)

mlx5e_vxlan_core_del_port_cmd cleared the wrong address, the address of
the pointer of the buffer rather than clearing the buffer itself.

This can lead to a serious stack corruption.

Fixes: b3f63c3d5e2c ("net/mlx5e: Add netdev support for VXLAN tunneling")
