From 94e4ee5395b437e9ddaec8cdea47c1a4a9ba0c01 Mon Sep 17 00:00:00 2001 From: Pavel Kubelun Date: Thu, 12 Feb 2015 09:49:08 +0800 Subject: [PATCH] net: ar8327: modify some configuration of switch Imported from https://source.codeaurora.org/quic/qsdk/system/openwrt/commit/?h=korg/linux-3.4.y/release/arugula_bb_cs&id=2be4f8a8b205ae1a37db44839864451ebe893e6e Signed-off-by: Pavel Kubelun Enable flow control of LAN and WAN ports to get better performance. Setup pvid as 0 for all ports during initialisation to avoid confusion during system or switch INIT. Disable PORT MAC before config MAC to avoid it work abnormal. This change is for IR-054144, IR-057315.
