From 27e9e10391259cbe2e52d6f0ac5b16b1d898d901 Mon Sep 17 00:00:00 2001 From: Ivan Khoronzhuk Date: Wed, 10 Aug 2016 02:22:32 +0300 Subject: [PATCH] net: ethernet: ti: cpsw: simplify submit routine As second net dev is created only in case of dual_emac mode, port number can be figured out in simpler way. Also no need to pass redundant ndev struct. Reviewed-by: Mugunthan V N Reviewed-by: Grygorii Strashko Signed-off-by: Ivan Khoronzhuk Signed-off-by: David S.
