[OpenWrt-Devel] Openvswitch package not available in trunk

Mon Aug 10 10:50:50 EDT 2015

Today I compiled with your fork and everything seemed fine at first.
After flashing to a TP-Link WDR3600 Router I can see the ovsdb-server running
and <ovs-vsctl show> reveals the usual String ID.

When I try to add a bridge with <ovs-vsctl add-br br0> the command does not return
to the input prompt. After pressing ctrl+c and checking <ovs-vsctl show> it seems like
the bridge was created. The same happens when adding ports or changing any
settings on the bridge.

Additionally, the switch does not connect to the controller. I'm not sure how to debug 
this further, but if you have an idea I will test it on the device.
