[OpenWrt-Devel] [PATCH 2/4] ar8216: add ARL table flushing per port

Sat Jan 31 04:28:13 EST 2015
Adds functions for flushing ARL table entries per port.
Successfully tested on AR8327. Implementation for AR8216/AR8236/AR8316
is based on the AR8236 datasheet and assumes that the three chips
share a common ATU register layout.
Compile-tested only for AR8216/AR8236/AR8316.
