From 8a44dbb202617aa66968ba74fdabf1b654dfe661 Mon Sep 17 00:00:00 2001 From: Roopa Prabhu Date: Thu, 29 Jan 2015 22:40:13 -0800 Subject: swdevice: add new apis to set and del bridge port attributes This patch adds two new api's netdev_switch_port_bridge_setlink and netdev_switch_port_bridge_dellink to offload bridge port attributes to switch port (The names of the apis look odd with 'switch_port_bridge', but am more inclined to change the prefix of the api to something else. Will take any suggestions). The api's look at the NETIF_F_HW_SWITCH_OFFLOAD feature flag to pass bridge port attributes to the port device. Signed-off-by: Roopa Prabhu Signed-off-by: David S.
