2015-03-30ath10k: bump up FW API to 5Kalle Valo
Firmware 10.2.4.48-3 now supports management frames over HTT feature and has ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX. But as 10.2.4 branch has conflicting HTT ids patch "ath10k: add ATH10K_FW_IE_HTT_OP_VERSION" is needed to fix the issue. Older ath10k versions don't have support that support and to maintain backwards compatibility we need bump up the FW API to 5 not break older versions.

2015-03-30ath10k: add ATH10K_FW_IE_HTT_OP_VERSIONRajkumar Manoharan
Target to host HTT messages are conflicting between 10.x and other firmware revisions. By maintaining separate HTT T2H tables for each firmware revisions (main, 10x and tlv) similar to WMI abstraction, solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can advertise the HTT interface to ath10k. This fix is needed to get management frames over HTT (ie. ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware. Otherwise there will be unknown htt events and nothing works: [30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled [30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled [30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT interface. That way old firmware images will still work.

2015-03-23ath10k: move driver state check before setting throttleRajkumar Manoharan
Since thermal daemon is unaware of the device state, it might try to adjust the throttle state when the device is powered down. So the driver caches the value and will configure it while powering up the target. The cached value will be programed later once the device is brought up. In such case, returning error status is confusing and misleading the user application. Hence moving the driver state check before sending wmi command to target.

2015-03-23ath10k: fix rts profile for second rate seriesRajkumar Manoharan
By default rts protection is enabled in firmware for the second rateset. Currently ath10k selects RTS profile (only for software retries), when legacy stations are associated or asked by mac80211. On congested environment, when AP is running in HT/VHT mode and there are no legacy clients associated, this will impact the robustness.

2015-03-20mac80211: avoid duplicate TX path station lookupJohannes Berg
Instead of looking up the destination station twice in the TX path (first to build the header, and then for control processing), save it when building the header and use it later in the TX path. To avoid having to look up the station in the many callers, allow those to pass %NULL which keeps the existing lookup. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-03-20mac80211: mesh: avoid pointless station lookupJohannes Berg
In ieee80211_build_hdr(), the station is looked up to build the header correctly (QoS field) and to check for authorization. For mesh, authorization isn't checked here, and QoS capability is mandatory, so the station lookup can be avoided. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-03-20mac80211: drop 4-addr VLAN frames earlier if not connectedJohannes Berg
If there's no station on the 4-addr VLAN interface, then frames cannot be transmitted. Drop such frames earlier, before setting up all the information for them. We should keep the old check though since that code might be used for other internally-generated frames. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2015-03-20mac80211: don't look up destination station twiceJohannes Berg
There's no need to look up the destination station twice while building the 802.11 header for a given frame if the frame will actually be transmitted to the station we initially looked up. This happens for 4-addr VLAN interfaces and TDLS connections, which both directly send the frame to the station they looked up, though in the case of TDLS some station conditions need to be checked. To avoid that, add a variable indicating that we've looked up the station that the frame is going to be transmitted to, and avoid the lookup/flag checking if it already has been done. In the TDLS case, also move the authorized/wme_sta flag assignment to the correct place, i.e. only when that station is really used. Before this change, the new lookup should always have succeeded so that the potentially erroneous data would be overwritten. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2015-03-19ath10k: protect driver from unsolicited htc ep0 eventsMichal Kazior
Some firmware revisions (tested with qca6174 rm2.0-00088) deliver unsolicited unknown (kind of garbled) HTC ep0 event to host in some cases. This issue was mainly observed with both qca988x and qca6174 being installed on a single host system. During driver probing if qca6174 booting sequences were somehow deferred (e.g. by qca988x implicitly making some resources busy presumably) the unsolicited event would came around 1s after ATH10K_HTC_MSG_READY_ID was delivered to host for qca6174. The unsolicited event would confuse driver and cause HTT initialization (and subsequently driver probing) to fail. Make the ep0 event processing more robust. The event will still be caught but instead will only generate a warning now. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

2015-03-19ath10k: strip qos data bit alwaysMichal Kazior
NativeWifi tx mode expects QoS Data frames to be delivered as Data frames with QoS part (e.g. tid) being delievered out-of-band in fw tx command. The QoS bit wasn't stripped before submitting to firmware. Stripping fixes two known problems: * qca6174 IOT with some APs, e.g. Cisco AIR-AP 1252 (which would crash after ath10k association). Some ath9k APs would crash as well. * sniffing own tx frames via radiotap because, e.g. wireshark was seeing QoS bit set but since QoS Control was stripped in ath10k it would parse beginning of LLC/SNAP >From debugability point of view this removes the ability to distinguish QoS from non-QoS frames when sniffing own tx via radiotap. On the other hand frames can be now parsed correctly without special software modification. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2015-03-17mac80211: Get IV len from key conf and not cipher schemeCedric Izoard
When a key is installed using a cipher scheme, set a new internal key flag (KEY_FLAG_CIPHER_SCHEME) on it, to allow distinguishing such keys more easily. In particular, use this flag on the TX path instead of testing the sta->cipher_scheme pointer, as the station is NULL for broad-/multicast message, and use the key's iv_len instead of the cipher scheme information.

2015-03-17mac80211: minstrel_ht: fix rounding issue in MCS duration calculationFelix Fietkau
On very high MCS bitrates, the calculated duration of rates that are next to each other can be very imprecise, due to the small packet size used as reference (1200 bytes). This is most visible in VHT80 nss=2 MCS8/9, for which minstrel shows the same throughput when the probability is also the same. This leads to a bad rate selection for such rates.

2015-03-07ath10k: fix interrupt stormVasanthakumar Thiagarajan
Promiscuous mode is enabled when wlan interface is added to bridge. ath10k creates a monitor mode when promiscuous mode is enabled. When monitor vdev is running along with other vdev(s) there is a huge number of interrupts generated especially in noisy condition. Fix this by not enabling promiscuous(monitor) mode when already a vdev is running. As disabling promiscuous mode may have issues with 4-address bridging in STA mode, the change is done specific to non-sta/ibss mode types. This does not change the support of virtual interface of type monitor along with other vdevs of any type. This could fix management frame drop in fw due to unavailable buffers because in monitor mode device receives everything seen on the air. In noisy condition, disabling monitor mode helps assoc go through without any issue.
