[ixp1200] How to communicate IXP1200 ENP2505 card with PC usi ng Ethernet ports

[Ye, Irvin]

Hi, Nimit,

I've tried Intel's samples, both l2bridge and l3forward, but failed to let them
work. There're always errors in the egress side. The ueng always stops to wait
for the ports to be ready, while the ports keep unready. Would you give me some
hints?

Irvin

Ning...
Try running the hardware version of the l3fwdr project on the IXP by
configuring it for the number of interfaces you want to use.
