From: Scott Feldman Date: Fri, 28 Nov 2014 13:34:30 +0000 (+0100) Subject: rocker: add ndo_bridge_setlink/getlink support for learning policy X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5111f80cbc759bed12941678bd029fca76512815;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git rocker: add ndo_bridge_setlink/getlink support for learning policy Rocker ports will use new "swdev" hwmode for bridge port offload policy. Current supported policy settings are BR_LEARNING and BR_LEARNING_SYNC. User can turn on/off device port FDB learning and syncing to bridge.
