problem with intercontinental TCP connections of over 4Gbit/s, which is where my test hardware runs out of bus bandwidth. Stuff that is on the TODO list: * HW VLAN support. * Large jumbo buffers (16k). * TCP Segmentation Offload * RAIDC (receive interrupt delay adaptation) * Understand how to use memory above 4GB.
