2015-04-01ath10k: fix IBSS scanning on wmi-tlv and qca6174Michal Kazior1-19/+12
WLAN.RM.2.0-00073 firmware requires self-peer to be created prior to issuing scan command. Without this wmi-tlv with qca6174 firmware crashes after submitting a scan request.

2015-04-01ath10k: allocate fw resources for iface combinationsMichal Kazior2-8/+6
The number of 3 vdevs wasn't enough to handle the worst case for interface combinations in practice. wpa_supplicant may need up to 4 vifs to have 2 vifs actually connected, i.e. p2pdev + client + 2x p2p (either p2p client or p2p go). This fixes worst case warning: Free vdev map is empty, no more interfaces allowed. This keeps the ability to associate 32 stations in AP mode at the cost of not being able to guarantee that under all circumstances, i.e. some combinations may consume additional fw peer entries for internal purposes leaving less resource for stations in AP mode.

2015-04-01ath10k: implement tx pause wmi eventMichal Kazior4-0/+187
qca6174 wmi-tlv firmware defines a new wmi event for host tx pausing (i.e. stop/wake tx queues). Map these events to ath10k/mac80211 tx queue control.

2015-04-01ath10k: fix survey reportingMichal Kazior2-1/+5
Number of channels is stored in a separate macro in a header file and channel list is constructed independently. The macro is used to define survey array. This fixes a recent regression introduced after adding support for 144 channel.

2015-03-30ath10k: rework legacy rx rate decodingMichal Kazior3-57/+46
Instead of using a hacky table and magic values use supported band information advertised to mac80211. This may impact performance a little when dealing with legacy rx rates depending on system architecture. It's probably negligible. This also fixes a highly theoretical corner case when HT/VHT rates weren't reported correctly if channel frequency wasn't known.

This will expose in /sys whether the ifname of a device is set by userspace or generated by the kernel. The latter kind (wlanX, etc) is not deterministic, so userspace needs to rename these devices to names that are guaranteed to stay the same between reboots. The former, however should never be renamed, so userspace needs to be able to reliably tell the difference.
