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

[Srinivasan Srikanth-R9AABP]

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
