Subject: mlx4_en: fix allocation of device tx_cq
From: Kleber Sacilotto de Souza <klebers@xxxxxxxxxxxxxxxxxx>
[ Upstream commit 427a96252d8eee7b9bbafce15bd37fa3387ede55 ]
The memory to hold the network device tx_cq is not being allocated with
the correct size in mlx4_en_init_netdev(). It should use MAX_TX_RINGS
instead of MAX_RX_RINGS. This can cause problems if the number of tx
rings being used is greater than MAX_RX_RINGS.
