[hpsdr] Ozy with Gb Ethernet

[Warren Walsh]

Funny you should mention the Xilinx Virtex-4FX. I just finished this
design<http://www.pentek.com/products/Detail.cfm?Model=7142>using the
XC4VFX60 and the XC4VSX55. They are nice parts, but not cheap and
are also BGA's. Now with the Virtex-5's now coming out these should go down
in price.

I really think that a GbE card is overkill this design. A 10/100BT card
might be better using an ARM7 processor and could be done fairly easily, at
lower cost. I'll continue my research and welcome all input.
