There are 3 network interfaces with different types being created when driver is loaded.

1. mlan0 (infra. STA)
2. uap0 (AP)
3. p2p0 (P2P_CLIENT)

Only mlan0 is for infra STA use. Doesn't the network manager check the type and only list the interface with STA type?

Comment 2 thariman 2013-08-15 23:31:48 UTC

It show all 3 interface and try to configure all 3 at the same times.
It asked 3 passphrase.

Comment 7 thariman 2013-08-26 08:14:26 UTC

Bing Zhao,

Doesn't look like this patch make it to rc7.  Is this going to be in the release version ?

Thank you

Comment 8 Bing Zhao 2013-08-26 18:57:45 UTC

It was submitted for 3.12.
If you want it in 3.11 we can resend the patch (with commit ID from linux.git) to 3.11-stable later.

Comment 9 thariman 2013-08-27 00:41:06 UTC

Bing Zhao,

Yes it would be nice if it will be in 3.11.
Otherwise it need to be done by all the distro.

Thank you.

Comment 10 Bing Zhao 2013-09-18 02:22:50 UTC

It's in linux-stable 3.11.1 now.
