* wifi: iwlwifi: mvm: fix kernel-doc warningsJohannes Berg2025-06-251-0/+1
| | | | | | | | Some kernel-doc warnings remain, fix them. Signed-off-by: Johannes Berg <[email protected]> Signed-off-by: Miri Korenblit <[email protected]> Link: https://patch.msgid.link/20250611222325.f238dd2937ed.I1b42df920b0f057a7d7ac01e61201621229a444c@changeid
* wifi: iwlwifi: handle v3 ratesJohannes Berg2025-05-071-1/+4
| | | | | | | | | | For UHR, a version 3 of the rate API is being added, which increases the number of bits used for MCSes by shifting the NSS bit up. Handle that.

* wifi: iwlwifi: mvm: revert gen2 TX A-MPDU size to 64Johannes Berg2024-05-291-7/+2
| | | | | | | | | | | | | | | We don't actually support >64 even for HE devices, so revert back to 64. This fixes an issue where the session is refused because the queue is configured differently from the actual session later.

* wifi: iwlwifi: mvm: move max_agg_bufsize into host TLC lq_staGregory Greenman2023-03-301-2/+4
| | | | | | | | | | | | This field is used only for host TLC, so it can reside inside the corresponding lq_sta struct. Also, TLC lq_sta is cleared in iwl_mvm_rs_rate_init() upon association, but max_agg_bufsize is set earlier in iwl_mvm_sta_init(). Thus, place this field in the persistent part of lq_sta to retain its value.

* iwlwifi: mvm: always init rs_fw with 20MHz bandwidth ratesNaftali Goldstein2018-08-311-1/+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.

* iwlwifi: mvm: Send LQ command as async when necessaryAvraham Stern2018-08-311-1/+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.

* iwlwifi: mvm: rs: introduce new API for rate scalingGregory Greenman2017-12-051-1/+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.

* iwlwifi: mvm: rs: start using LQ command colorGregory Greenman2017-06-051-0/+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.
