[U-Boot] Support in u-boot for PCI-Express NIC

Hi,

Is there support under u-boot for newer pcie network cards? Under drivers/net, I notice that there is the e1000 and sk98 network drivers. Unfortunately, these seem a bit dated and the pcie x1 nic/s I am trying to use are not supported (checked the device ids). Pointers on any other supported pcie nic will be helpful.

Thanks, ~Sri
