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 here: http://dev.laptop.org/pub/firmware/libertas/ Signed-off-by: Ashish Shukla <ashishs@marvell.com> Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.
