I'll point out the obvious here. If it's purely-local, then there's no need to deal with the TCP/IP stack--raw ethernet frames would work just fine, and cut-out much of the processing you're complaining about. I'd configure things with a 1GigE card for the radio data grabber, and another card for my real network traffic. -- Marcus Leech Mail: Dept 1A12, M/S: 04352P16 Security Standards Advisor Phone: (ESN) 393-9145 +1 613 763 9145 Advanced Technology Research Nortel Networks [EMAIL PROTECTED] _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
