libertas: separate mesh connectivity from that of the main interface
The transmit and receive traffic as soon as the mesh interface is
brought up.
Test case 1: Bring up only the mesh interface and ping. No need for
any iwconfig commands on the main interface.
$ ifconfig msh0 192.168.5.3
$ iwconfig msh0 channel X
$ ping 192.168.5.2
If ping succeeds, PASS
Test case 2: Associate with the main interface, and turn off AP. Mesh
interface should not lose connectivity.
$ iwconfig eth0 mode managed essid "my_ssid"
$ ifconfig msh0 192.168.5.3
$ ping 192.168.5.2
<turn off access point>
If ping continues uninterrupted, PASS
This feature requires firmware version 5.110.19.p0 or newer, available
