Linux networking on Juno board

Hi,

I have the Juno board booting with the Linaro Linux rootfs and kernel version 3.10.52.  I see an eth0 device inside of Linux, and from the boot messages, I see that it's trying to DHCP an address, but neither DHCP nor assigning a static IP to the interface brings up a working network.  Prior to booting Linux, if I start the FTP server from the Cmd> prompt I do get an address and the FTP server starts, so I know that the network connection itself is good.  Should the ethernet interface work inside of Linux?

I've also tried recompiling the kernel to enable USB networking, which kind of works. But the ASIX AX88772 drivers tend to crash the kernel after a short time.  If I need to use a USB-> ethernet adapter, are there recommendations for adapters that are known to work well?

thanks,

JP
