The port(eth1) connected to gigabit ethernet can't send data.
I use "ping" to check the connection. It always timeout.
When the giagabit ethernet cable pluged in the board, system also show :
eth1: link up (1000Mbps/Full duplex)
br-lan: port 1(eth1) entering forwarding state

My platform refer to Atheros AP96.AR8021 is gigabit ethernet phy.

And it is connected to 100M ethernet is ok.(everything is ok in 100M)
I have no idea where need be modified to let 1000M work.
Help me!

Besides, Should I care "ar71xx_eth1_pll_data.pll_1000" value?

I'm 99% sure it's the pll value. Check the the datasheets of the ar7161 and ar8021 to find out what the correct value is.
