50Mhz to 60Mhz

Dear friend,

Thank you ver much for your reply!

I met another very strange question!

my nios2 is 50Mhz, and I have tested the netport for a long time.

but the net port is wrong sometimes, while the config is ok ,accessed through nios2-terminal!

# ifconfig

I think that my PC is OK, but ping is not ok!
