2017-08-01iwlwifi: reorganize firmware APIJohannes Berg1-917/+0
Apart from DVM, all firmware uses the same base API, and there's code outside iwlmvm that needs to interact with it. Reflect this in the source better and reorganize the firmware API to a new fw/api/ directory. While at it, split the already pretty large fw-api.h file into a number of smaller files, going from almost 3k lines in there to a maximum number of lines less than 1k.

2017-06-29iwlwifi: mvm: support multi tid ba notifLiad Kaufman1-1/+3
When receiving a BA_NOTIF on new TX API, it can contain BAs for several TIDs. Go over them and reclaim TX for every TID. Note that although the small API change, the API version still isn't bumped forward, as this NIC isn't still officially released.

2017-06-29iwlwifi: mvm: fix various "Excess ... description" kernel-doc warningsJohannes Berg1-1/+0
Fix various "Excess struct/union/enum/typedef member '...' description in '...'" warnings from kernel-doc, mostly caused by typos. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2017-06-23iwlwifi: mvm: support new flush APIMordechai Goodstein1-1/+13
This new API allows flushing queues based on station ID and TID in A000 devices. One reason for using this is that tfd_queue_mask is only good for 32 queues, which is not enough for A000 devices.

This improves documentation, since kernel-doc can't deal with the union well. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-06-12Merge tag 'iwlwifi-next-for-kalle-2017-06-06' of ↵Kalle Valo1-39/+28
git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/iwlwifi-next First batch of iwlwifi driver patches 4.13 * Loads of FW API documentation improvements (for tools and htmldoc); * Continued work for the new A000 family; * Bumped the maximum supported FW API to 31; * Improve the differentiation between 8000, 9000 and A000 families; * A lot of fixes and cleanups here and there; kvalo: There were conflicts iwl_mvm_stop_device() and iwl_mvm_tcool_set_cur_state(). The former was easy but latter needed more thought. Apparently the mutex was taken too late, so I fixed so that the mutex is taken first and then check for iwl_mvm_firmware_running().
2017-06-05iwlwifi: mvm: rs: start using LQ command colorGregory Greenman1-0/+3
Up until now, the driver was comparing the rate reported by the FW and the rate of the latest LQ command to avoid processing data belonging to the old LQ command. Recently, FW changed the meaning of the initial rate field in tx response and it holds the actual rate (which is not necessarily the initial rate of LQ's rate table). Use instead LQ cmd color to be able to filter out tx responses/BA notifications which where sent during earlier LQ commands' time frame. This fixes some throughput degradation in noisy environments.

2017-06-02iwlwifi: mvm: use proper sta_addr in firmware APIJohannes Berg1-4/+2
There's no point to declare an address as a __le32/__le16 and then only take a pointer to it anyway, change that to just a sta_addr[ETH_ALEN]. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2017-04-19iwlwifi: mvm: support new TX response for TVQMSara Sharon1-24/+18

2017-04-19iwlwifi: mvm: support new TX APISara Sharon1-1/+41

2016-09-26iwlwifi: remove support for fw older than -17 and -22Luca Coelho1-2/+0
FW versions older than -17 for 3160 and 7260 and older than -22 for newer NICs are not supported anymore. Don't load these versions and remove code that handles them. Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2016-07-06iwlwifi: mvm: add support for GCMP encryptionAyala Beker1-8/+23
Newer hardware supports GCMP and GCMP 256-bit ciphers. Add support for adding/setting GCMP key for TX mode. In the TX command handling GCMP-256 is handled in a different way as the key size should be up to 128-bits: Set the key value to the key index in the key table, and specify that this key should be taken form the key table instead of from the TX command. While at it - convert security control flags to an enum. Signed-off-by: Ayala Beker <ayala.beker@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-07-01iwlwifi: mvm: Support CSA countdown offloadingAndrei Otcheretianski1-3/+24
Add support CSA countdown offloading. When CSA starts, the driver specifies the offsets to the eCSA and CSA IEs in the beacon template command and the fw performs the countdown. The fw notifies the driver when the channel switch flow should be performed. Beacon sent notifications are not used anymore.

2016-03-30iwlwifi: mvm: add support for new TX CMD APISara Sharon1-2/+33
TX CMD API has changed to support offload assist. Currently we do not enable checksum yet, but must set the padding indication, to avoid FW errors. Set other amsdu flag as well. The rest of the flags will be configured only if HW csum is enabled and will be set in future patches. This change is backward compatible.

2016-01-26iwlwifi: mvm: rs: fix TPC statistics handlingGregory Greenman1-1/+5
FW behaviour changed and now updates driver about the used TPC reduction in the following cases: 1. In tx response, which is used mostly for a single frame case 2. In BA notification When tx aggregation fails with the initial rate, FW will send to the driver BA notification and will try to transmit with the next rate, but this time without tx power reduction. Thus, in case of a failure with the initial rate, driver will get two BA notifications, the first one with reduced tx power as in the LQ command and the second one with 0 power reduction. This patch adapts the TPC statistics according to the description above: 1. Use BA notifications instead of Tx response 2. For TPC only, drop the optimization which considers empty BA as one MPDU. The reason is that with TPC we want to recover very quickly from a bad power reduction and, therefore we'd like the success ratio to get an immediate hit when failing to get a BA, so we'd switch back to a lower or zero power reduction Signed-off-by: Gregory Greenman <gregory.greenman@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com>
