Subject: wl12xx: support p2p interfaces
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=045c745f8ccdb584ccc97f068c7c10c1090fbcf9;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

wl12xx: support p2p interfaces

Declare support for p2p interfaces, and create p2p_cli/p2p_go
roles when being asked for.

Indicate we are using a p2p interface by setting the wl->p2p flag.
