the PCIX bus start to get heavily loaded. This only happen when using
chained descriptors, therefore work-around it by providing a private
pool of receive buffers able to contain a full-sized packet.
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.
