Subject: [PATCH] net/mlx4_en: Fix an error handling path in 'mlx4_en_init_netdev()'
Date: Tue,  8 May 2018 11:34:26 +0200	[thread overview]
Message-ID: <20180508093426.11550-1-christophe.jaillet@wanadoo.fr> (raw)

If the 2nd memory allocation of the loop fails, we must undo the
memory allocation done so far.

Fixes: 67f8b1dcb9ee ("net/mlx4_en: Refactor the XDP forwarding rings scheme")
