Fix kernel network config parameters in sysctl.conf
I've got some settings that seem to work okay. At least the video isn't dropping out completely. But I still get frozen playback on the player.
The updates are on the RPI2 server and the media player boxes. I may need a few others (see my browser tabs on galileo). The same configs are needed in both server and player. I also have updates in /etc/init.d/S40Network to set txlength for wlan0.
I've ordered a 1G network switch and some cables. If that works more consistently I may have to switch to a wired demo.
