Hi,
I think brcmfmac may have some problems with mixing various
interfaces, so just for some test I decided to try p2p interface. I'm
using BCM43602 and it seems to support p2p:
# iw phy phy0 info | tail
valid interface combinations:
* #{ IBSS, managed }<= 1, #{ AP }<= 4, #{
P2P-client, P2P-GO }<= 1, #{ P2P-device }<= 1,
total<= 3, #channels<= 1
But I can't create p2p interface:
# iw phy phy0 interface add p2p0 type __p2pdev
brcmfmac: brcmf_add_if: ERROR: netdev:wlan0 already exists
brcmfmac: brcmf_add_if: ignore IF event
brcmfmac: brcmf_p2p_set_firmware: failed to update device address ret -52
brcmfmac: brcmf_p2p_create_p2pdev: set p2p_disc error
command failed: Invalid exchange (-52)
This looked familiar so digging the log I think you need the following

brcmfmac: assure P2P discovery is disabled when setting P2P_DEVICE
mac addre
In order to provision the P2P_DEVICE mac address using
p2p_da_override iovar
the discovery interface must be disabled. On some targets setting
the mac
address failed so disable the discovery interface to be certain.

Not sure what kernel and/or brcmfmac you are seeing this so hopefully
this commit will help.
