Hello,
With latest compat, wpa_supplicant seems p2p_concurent is set for
car9170 driver based on information from driver.
So, next after p2p_group_add new virtual interface is created for that
- p2p-wlan0-0.
Next, carl9170_op_add_interface() return -EBUSY because there is
already main_vif (NL80211_IFTYPE_STATION) created by default on
startup.
Because of that p2p_group_add() always fail with such chipset and
p2p_concurent=1.
STEPS:
- run wpa_supplicant
- run wpa_cli
- p2p_group_add
FAIL
Is that chipset limitation we could add only new STA interface when
main_vif is also STA?
Where could I find HW documentation for carl9170?
I suspect lower change is not acceptable because of HW limitation?
main_vif = carl9170_get_main_vif(ar);
if (main_vif) {
switch (main_vif->type) {
case NL80211_IFTYPE_STATION:
- if (vif->type == NL80211_IFTYPE_STATION)
+ if ((vif->type == NL80211_IFTYPE_STATION) ||
+ (vif->type == NL80211_IFTYPE_AP))
break;
