From: Brajesh Dave <brajeshd@xxxxxxxxxxx> 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@xxxxxxxxxxx> Signed-off-by: Javier Cardona <javier@xxxxxxxxxxx> Signed-off-by: Dan Williams <dcbw@xxxxxxxxxx> diff --git a/drivers/net/wireless/libertas/cmd.c b/drivers/net/wireless/libertas/cmd.c index 5b2a1c7..b4d1b14 100644 --- a/drivers/net/wireless/libertas/cmd.c +++ b/drivers/net/wireless/libertas/cmd.c @@ -1755,7 +1755,8 @@ int lbs_execute_next_command(lbs_private * priv) */ if ((adapter->psmode != LBS802_11POWERMODECAM) && (adapter->psstate == PS_STATE_FULL_POWER) && - (adapter->connect_status == LBS_CONNECTED)) { + ((adapter->connect_status == LBS_CONNECTED) || + (adapter->mesh_connect_status == LBS_CONNECTED))) { if (adapter->secinfo.WPAenabled || adapter->secinfo.WPA2enabled) { /* check for valid WPA group keys */ diff --git a/drivers/net/wireless/libertas/cmdresp.c b/drivers/net/wireless/libertas/cmdresp.c index 6c1fdb8..11b93f2 100644 --- a/drivers/net/wireless/libertas/cmdresp.c +++ b/drivers/net/wireless/libertas/cmdresp.c @@ -979,7 +979,7 @@ int lbs_process_event(lbs_private * priv) break;
