Digging down a little further, it would be interesting to consider
what EtherType (http://en.wikipedia.org/wiki/EtherType) would be most
appropriate for use for OzyII (and/or other SDR applications). My
thought is that we should try to select an existing EtherType with the
most compatibility with current and future Ethernet switching/bridging
devices as opposed to selecting our own or using some existing but
obscure EtherType value that is either incompatible or not well tested
with a broad range of Ethernet hardware. It might also be worth
considering using an IEEE 802.2 header instead of an EtherType, since
it would allow some rudimentary broadcast and routing capabilities.

How about something like EtherType 0x8906 (Fibre Channel over
Ethernet), since what we want to do basically is to ship a lot of data
from an ADC and/or FPGA decimator to another host?
