This per TID configurations are passed in NL80211_ATTR_TID_CONFIG which is a nested attribute. This patch adds support to configure per TID noack policy through NL80211_ATTR_TID_CONFIG_NOACK attribute. Data TID value for this configuration will be passed through NL80211_ATTR_TID_CONFIG_TID attribute. When the user-space wants this configuration peer specific rather than being applied for all the connected stations, MAC address of the peer can be passed in NL80211_ATTR_MAC attribute. This patch introduced enum ieee80211_tid_conf_mask to notify the driver that which configuration modified. Driver supporting data TID specific noack policy configuration should be advertise through NL80211_EXT_FEATURE_PER_TID_NOACK_CONFIG and supporting per STA data TID noack policy configuration should be advertise through NL80211_EXT_FEATURE_PER_STA_NOACK_CONFIG Signed-off-by: Tamizh chelvam --- include/net/cfg80211.h | 35 +++++++++++++++ include/uapi/linux/nl80211.h | 51 ++++++++++++++++++++++ net/wireless/nl80211.c | 102 +++++++++++++++++++++++++++++++++++++++++++ net/wireless/rdev-ops.h | 11 +++++ net/wireless/trace.h | 18 ++++++++ 5 files changed, 217 insertions(+) diff --git a/include/net/cfg80211.h b/include/net/cfg80211.h index f81677f..07eb2de 100644 --- a/include/net/cfg80211.h +++ b/include/net/cfg80211.h @@ -509,6 +509,35 @@ struct cfg80211_chan_def { u32 center_freq2; }; +enum ieee80211_tid_conf_mask { + IEEE80211_TID_CONF_NOACK = BIT(0), +}; + +/** + * struct ieee80211_tid_cfg - TID specific configuration + * @tid: TID number + * @tid_conf_mask: bitmap indicating which parameter changed + * see %enum ieee80211_tid_conf_mask + * @noack: noack configuration value for the TID + */ +struct ieee80211_tid_cfg { + u8 tid; + enum ieee80211_tid_conf_mask tid_conf_mask; + u8 noack; +}; + +/** + * struct ieee80211_tid_config - TID configuration + * @peer: Station's MAC address + * @n_tid_conf: Number of TID specific configurations to be applied + * @tid_conf: Configuration change info + */ +struct ieee80211_tid_config { + const u8 *peer; + u32 n_tid_conf; + struct ieee80211_tid_cfg tid_conf[]; +}; + /** * cfg80211_get_chandef_type - return old channel type from chandef * @chandef: the channel definition @@ -3436,6 +3465,10 @@ struct cfg80211_pmsr_request { * Statistics should be cumulative, currently no way to reset is provided. * @start_pmsr: start peer measurement (e.g. FTM) * @abort_pmsr: abort peer measurement + * @set_tid_config: TID specific configuration.

This will be useful for the driver which supports data TID specific retry count configuration rather using phy level retry configuration. This TID specific retry configuration will have more precedence than phy level configuration. This configuration can be applied for a specific peer. To apply this configuration specific to a peer rather than being applied for all the connected stations, MAC address of the peer can be passed in NL80211_ATTR_MAC attribute. Driver should advertise WIPHY_FLAG_HAS_MAX_DATA_RETRY_COUNT and max_data_retry_count value to notify user space to avoid of passing greater than the allowed limit. Driver supporting TID specific retry configuration should advertise NL80211_EXT_FEATURE_PER_TID_RETRY_CONFIG and per STA specific data TID retry configuration should advertise NL80211_EXT_FEATURE_PER_STA_RETRY_CONFIG.

TID for which the this configuration is to be applied is passed in NL80211_ATTR_TID_CONFIG_TID attribute. TX bitrate mask values passed in NL80211_ATTR_TX_RATES attribute and NL80211_ATTR_TID_CONFIG_TX_RATES attribute will have types of the TX rate should be applied. When the user-space wants this configuration peer specific rather than being applied for all the connected stations, MAC address of the peer can be passed in NL80211_ATTR_MAC attribute. NL80211_ATTR_TX_RATES attribute can hold single value at a time, so the TX bitrate configuration can be set one TID at a time. Driver supporting this feature should advertise NL80211_EXT_FEATURE_PER_TID_TX_BITRATE_MASK and supporting per-STA data TID TX bitrate configuration should advertise NL80211_EXT_FEATURE_PER_STA_TX_BITRATE_MASK.

STA information along with the TID config change mask to notify driver that which configuration needs to be applied for this current command. If the STA info not available in the command then the configuration will be applied for all connected stations in the vif. TID specific noack configuration requires aggregation disabled and rate for the data TID packets should be basic rates. So, if the TID already configured with noack policy then driver will ignore the aggregation or TX rate related configuration for the same data TID. In TX rate configuration should be applied with highest preamble configuration(HT rates should not be applied for the station which supports vht rates). Vif specific TID configuration will be applied for all the connected stations except for the station which already applied with the same configuration for the TID through station specific command. Newly connecting stations will be applied with vif TID configuration which will be stored in ieee80211_vif.

Tx rate limit is similar to auto rate but it will be limited to the user configured rate mask rather than the station's highest supported rate mask. Here ext_tid_cfg_bitmap added to notify the target which extended configuration parameter has modified(here RTS_CTS). WMI_10_4_SERVICE_EXT_PEER_TID_CONFIGS_SUPPORT service flag introduced to advertise this support.
