I'm using a beaglebone black to stream video over UDP. I wrote a
software and have tested it using a urtwn device + webcam Logitech C920.
All is connected using a USB hub with external power source. So urtwn
and webcam, both are plugged in the same USB hub. When I plug the hub
and run my software on a old notebook intel centrino with FreeBSD
11.0-RC2 AMD64 all works fine. Last night the system stream video all
night. But, when I replace the notebook by beaglebone black running
FreeBSD 11.0-RC1 with the same USB HUB, the same wrtwn device and same
camera, randomly after some time the beaglebone black network shutdown
and terminal shows this messages :
Network is down

Then, I need to run
/etc/rc.d/netif stop
/etc/rc.d/netif start
To enable network again. So, someone can give me a hit about what can be
this and how to fix?
Thanks a lot
