From bfa0914afa95d44df9e1a1553e0c03a991223db3 Mon Sep 17 00:00:00 2001 From: Nicolas Ferre Date: Tue, 31 Mar 2015 15:01:59 +0200 Subject: [PATCH] net/macb: only probe queues once and use stored values When merging at91_ether and macb driver during 421d9df0628b (net/macb: merge at91_ether driver into macb driver) the probe function has been split. The code dealing with initialization of queues is now moved in macb_init() which needs information computed in the parent macb_probe() function. So, add the queue_mask information to the private structure and use it when needed in macb_init(). Signed-off-by: Nicolas Ferre Acked-by: Boris Brezillon Cc: Cyrille Pitchen Signed-off-by: David S.
