Bug 60747 - 1286:2044 [Microsoft Surface Pro]
|
|
Marvell 88W8797 wifi show 3 interface under network
|
|
https://bugzilla.kernel.org/show_bug.cgi?id=60747
|
|
|
|
This issue was also reported previously by OLPC and some folks from
|
|
the community.
|
|
|
|
There are 3 network interfaces with different types being created
|
|
when mwifiex driver is loaded:
|
|
|
|
1. mlan0 (infra. STA)
|
|
2. uap0 (AP)
|
|
3. p2p0 (P2P_CLIENT)
|
|
|
|
The Network Manager attempts to use all 3 interfaces above without
|
|
filtering the managed interface type. As the result, 3 identical
|
|
interfaces are displayed under network manager. If user happens to
|
|
click on an entry under which its interface is uap0 or p2p0, the
|
|
association will fail.
|
|
|
|
Work around it by removing the creation of AP and P2P interfaces
|
|
at driver loading time. These interfaces can be added with 'iw' or
|
|
other applications manually when they are needed.
