From: Vivien Didelot Date: Fri, 27 Jan 2017 20:29:39 +0000 (-0500) Subject: net: dsa: store a dsa_port in dsa_slave_priv X-Git-Tag: v4.11-rc1~124^2~293^2~5 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=afdcf151c1f7346207dcee3f8d6d82991dbbb7e5;p=platform%2Fkernel%2Flinux-exynos.git net: dsa: store a dsa_port in dsa_slave_priv Store a pointer to the dsa_port structure in the dsa_slave_priv structure, instead of the switch/port index. This will allow to store more information such as the bridge device, needed in DSA drivers for multi-chip configuration. Signed-off-by: Vivien Didelot Signed-off-by: David S.
