Hello, We had one environment where the NIC understood by u-boot and the NIC understood by the kernel where different. We just attached both to the same VLAN. During u-boot one was used for downloading the kernel, then once the kernel booted the other was used. Not ideal, and maybe not important enough to keep the "feature" around, but it does get used now and again.
