So far support for multiple interface was somehow broken in brcmfmac. Driver couldn't correctly match firmware and system interfaces resulting in not working APs and WARNINGs. This pending patches fixes that :) Signed-off-by: Rafał Miłecki <zajec5@gmail.com> SVN-Revision: 46734

Subject: [PATCH] brcmfmac: correct detection of p2pdev interface event
|
|
|
|
The p2pdev interface is setup in firmware resulting in a interface
|
|
event. This event has role and no-if flag. When role is p2p client
|
|
and no-if flag is set it indicates that this is the p2pdev interface.
|
|
This info is used in handling the event and adding interface in the
|
|
driver.
