[ath6kl]: Concurrent mode (STA+P2P) or (AP+P2P)

[Mike Engel]

Hi all,

we are using the kernel version 3.14 with the Atheros driver and we
would like to use concurrent mode. We have the latest firmware version
(fw-4) on the file system. We would like to use STA+P2P in concurrent
mode that should work with the wireless chip.

We are using this command sequence:

> iw dev wlan0 interface add wlan1 type managed
> ifconfig wlan1 up
> wpa_cli
> p2p_find

If we try to connect to a device with

p2p_connect <device_mac> pbc auth

we get the following error.

ath6kl: Not a supported interface type

To make AP+STA working in the Atheros driver we did this change to the driver.

static const struct ieee80211_iface_limit if_limits[] = {
    { .max = 2, .types = BIT(NL80211_IFTYPE_STATION) },
    { .max = 1, .types = BIT(NL80211_IFTYPE_AP) },
};

static const struct ieee80211_iface_combination if_comb[] = {
    {
        .limits = if_limits,
        .n_limits = ARRAY_SIZE(if_limits),
        .max_interfaces = 2,
        .num_different_channels = 1,
        .beacon_int_infra_match = true,
    },
};

Doing the same for STA+P2P doesn't seem to work.

Any information or help is appreciated .

Thanks,
