2018-08-31iwlwifi: mvm: always init rs_fw with 20MHz bandwidth ratesNaftali Goldstein1-1/+1
As with the non-offloaded rs case, during assoc on the ap side the phy context is set to 20MHz until authorization of a client that supports wider channel-widths. Support this by sending the initial tlc_config_cmd with max supported channel width of 20MHz until authorization succeeds.

2018-08-31iwlwifi: mvm: Send LQ command as async when necessaryAvraham Stern1-1/+1
The parameter that indicated whether the LQ command should be sent as sync or async was removed, causing the LQ command to be sent as sync from interrupt context (e.g. from the RX path). This resulted in a kernel warning: "scheduling while atomic" and failing to send the LQ command, which ultimately leads to a queue hang. Fix it by adding back the required parameter to send the command as sync only when it is allowed.

2018-07-26iwlwifi: add support for IEEE802.11axLuca Coelho1-4/+17
Add support for the HE in the iwlwifi driver conforming with P802.11ax_D2.0. Signed-off-by: Luca Coelho <[email protected]>
2018-05-30iwlwifi: mvm: open BA session only when sta is authorizedGregory Greenman1-5/+2
Currently, a BA session is opened when the tx traffic exceeds 10 frames per second. As a result of inter-op problems with some APs, add a condition to open BA session only when station is already authorized. Fixes: 482e48440a0e ("iwlwifi: mvm: change open and close criteria of a BA session") Signed-off-by: Gregory Greenman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-04-20iwlwifi: mvm: update rs-fw APINaftali Goldstein1-2/+0
Update rs-fw API to match changes in FW. Specifically, the TLC_MNG_NOTIF_REQ_CMD command and TLC_MNG_AMSDU_ENABLE_NOTIF notification are removed, the A-MSDU related info is received from FW via the TLC_MNG_UPDATE_NOTIF, and the TLC_MNG_CONFIG_CMD uses version 2 of its data structure. Additionally, constify some arguments in a couple of functions. Signed-off-by: Naftali Goldstein <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2018-04-20iwlwifi: mvm: support offload of AMSDU rate controlGregory Greenman1-1/+4
Support the new APIs and activate AMSDU based on the offloaded TLC decisions. Signed-off-by: Sara Sharon <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-12-05iwlwifi: mvm: rs: new rate scale API - add FW notificationsGregory Greenman1-0/+1
This patch sends to the FW notification configuration command and handles the update responses. Signed-off-by: Gregory Greenman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-12-05iwlwifi: mvm: rs: add basic implementation of the new RS API handlersGregory Greenman1-0/+2
This patch adds rate scaling configuration command and implements a few other handlers. Signed-off-by: Gregory Greenman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-12-05iwlwifi: mvm: rs: add ops for the new rate scaling in the FWGregory Greenman1-0/+14
This patch introduces a new instance of rate_control_ops for the new API (adding only empty stubs here and the subsequent patches in the series will fill in the implementation). The decision which API to use is done during the register step according to FW TLV. Signed-off-by: Gregory Greenman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-12-05iwlwifi: mvm: rs: introduce new API for rate scalingGregory Greenman1-1/+32
New devices will have rate scaling algorithm running in the firmware. With this feature, the driver's responsiblity is to provide an initial configuration and to handle notifications regarding recent rates and some other parameters. Debugfs hooks will be still available for reading the current rate/statistics and setting a fixed rate. The old API is supported so far, though both APIs cannot be used simultaneously. This is the first patch in the series. It adds a new TLV specifying FW support for the new API and updates lq_sta to support two types of rate scaling.

2017-06-29iwlwifi: mvm: support aggs of 64 frames in A000 familyLiad Kaufman1-0/+2
A SCD bug was fixed in the A000 family, allowing to support aggregations of 64 frames (rather than 63). Signed-off-by: Liad Kaufman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2017-06-05iwlwifi: mvm: rs: start using LQ command colorGregory Greenman1-0/+15
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.

2016-07-06iwlwifi: mvm: rs: add rate scaling support for 160MHz channelsGregory Greenman1-0/+1
Expand TLC to support 160MHz channels. Full support for A-MSDU case will be added separately. Signed-off-by: Gregory Greenman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-07-06iwlwifi: mvm: Do not open aggregations for null data packetsMatti Gottlieb1-1/+1
Currently we try to open an aggregation for every packet (given that one is not already open). This causes redundant overhead (addba/delba) for null data packets. Do not open an aggregation for null data packets. Signed-off-by: Matti Gottlieb <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-04-12cfg80211: remove enum ieee80211_bandJohannes Berg1-2/+2
This enum is already perfectly aliased to enum nl80211_band, and the only reason for it is that we get IEEE80211_NUM_BANDS out of it. There's no really good reason to not declare the number of bands in nl80211 though, so do that and remove the cfg80211 one. Signed-off-by: Johannes Berg <[email protected]>
