[Discuss-gnuradio] Setting UHD kernel buffers

[Charles Brain]

When setting the kernel max buffers for UHD the manual
suggests using 
sudo sysctl -w net.core.rmem_max=<new value>
sudo sysctl -w net.core.wmem_max=<new value>

I have done that on my system and it has made a huge difference to
the performance of my software. I can now transmit my DVB-T 
signal continuously at 10 Ms/s with no dropouts.

Unfortunately everytime I reboot my system I have to run the commands
again. What is the procedure for making these settings permanent?
I am no Linux guru hence the question. I am using Fedora 12.
