Routing performance (Buffalo WZR-HP-G301NH)

[Mori Hiroki]

Hi

I remember WZR-HP-AG301H. This target arge hints was very worry.

In Zrouter boards/Buffalo/WZR-HP-G301NH/board.hints

#hint.arge.0.media=1000 
hint.arge.0.media=100 
hint.arge.0.fduplex=1 
hint.arge.0.phymask=0x0

# This is RTL8366RB revision setting
hint.arge.0.miimode=3   # RGMII
hint.arge.1.miimode=3   # RGMII
hint.arge.0.pll_1000=0x1f000000
hint.arge.1.pll_1000=0x100

hint.arge.1.phymask=0x10
hint.arge.1.mdio=mdioproxy0                                                    
hint.arge.1.eeprommac=0xbfff120c

hint.rtl8366rb.0.phy4cpu=1

This setting is work only 100baseTX.

ifconfig and etherswich command say arge is 100baseTX.

pll_1000 value get from dd-wrt.
