Re: [Discuss-gnuradio] Netgear GA311 (Realtek 8169) and USRP 2

[Matt Ettus]

OK, it looks like we have some sort of problem with the RTL8169.  Can 
you guys run the following program in its own window

       while ip -s link show dev eth0 | more -c && sleep 1 ; do : ;done

That will show you stats on the ethernet device.  Then run find_usrps 
and see how many packets, drops, and errors see what happens.  Do the 
same thing for when you run usrp2_siggen.

Also, please run ifconfig and send the output.

Thanks,
Matt
