Add infrastructure to support per TID configurations like noack policy,
retry count, AMPDU control(disable/enable), RTSCTS control(enable/disable)
and TX rate mask configurations.
This will be useful for the driver which can supports data TID
specific configuration rather than phy level configurations.
Here NL80211_CMD_SET_TID_CONFIG added to support this operation by
accepting TID configuration.
This command can accept STA mac addreess to make the configuration
station specific rather than applying to all the connected stations
to the netdev.
And this nested command configuration can accept multiple number of
data TID specific configuration in a single command,
enum ieee80211_tid_conf_mask used to notify the driver that which
configuration got modified for the TID.

1.9.1
Add a new NL command, NL80211_CMD_SET_TID_CONFIG to support
data TID specific configuration. 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

Introduce NL80211_ATTR_TID_CONFIG_RTSCTS_CTRL in nl80211_attr_tid_config
to accept TID specific RTS_CTS enable/disable configuration
through NL80211_CMD_SET_TID_CONFIG command. TID for which the
RTS_CTS control configuration is to be applied is passed in
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.
Driver supporting this feature should advertise
NL80211_EXT_FEATURE_PER_TID_RTSCTS_CTRL and supporting per-STA data TID
RTS_CTS configuration should advertise NL80211_EXT_FEATURE_PER_STA_RTSCTS_CTRL.

1.9.1
This patch introduced below NL attributes to add support for
configuring data TID specific retry count
NL80211_ATTR_TID_CONFIG_RETRY
NL80211_ATTR_TID_CONFIG_RETRY_LONG
NL80211_ATTR_TID_CONFIG_RETRY_SHORT
These attributes are added in NL80211_ATTR_TID_CONFIG nested attribute.
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.

1.9.1
Introduce NL80211_ATTR_TID_CONFIG_AMPDU_CTRL in nl80211_attr_tid_config
to accept TID specific AMPDU aggregation enable/disable configuration
through NL80211_CMD_SET_TID_CONFIG command. TID for which the
aggregation control configuration is to be applied is passed in
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.
Driver supporting this feature should advertise
NL80211_EXT_FEATURE_PER_TID_AMPDU_CTRL and supporting per-STA data TID
ampdu configuration should advertise NL80211_EXT_FEATURE_PER_STA_AMPDU_CTRL.

1.9.1
This patch add ops for set_tid_config to support TID
specific configuration. 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.
Testing:
* Tested HW: QCA9888
* Tested FW: 10.4-3.5.1-00052

1.9.1
This patch adds WMI interface to configure station specific
TID configuration . Host needs to send station's MAC address
along with TID number and its configuration to target through
WMI_10_4_PER_PEER_PER_TID_CONFIG_CMDID.
WMI_SERVICE_PEER_TID_CONFIGS_SUPPORT flag is added to advertise
this support.

* Tested HW: QCA9888
* Tested FW: 10.4-3.5.1-00052

1.9.1
This patch extend TID configuration support to configure
RTS_CTS control and TX rate limit. 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.

Hello Tamizh,
> Add infrastructure to support per TID configurations like noack policy,
> retry count, AMPDU control(disable/enable), RTSCTS control(enable/disable)
> and TX rate mask configurations.
> This will be useful for the driver which can supports data TID
> specific configuration rather than phy level configurations.
> Here NL80211_CMD_SET_TID_CONFIG added to support this operation by
> accepting TID configuration.
> This command can accept STA mac addreess to make the configuration
> station specific rather than applying to all the connected stations
> to the netdev.
> And this nested command configuration can accept multiple number of
> data TID specific configuration in a single command,
> enum ieee80211_tid_conf_mask used to notify the driver that which
> configuration got modified for the TID.
>
> Tamizh chelvam (9):
> nl80211: New netlink command for TID specific configuration
> nl80211: Add new netlink attribute for TID speicific retry count
> nl80211: Add netlink attribute for AMPDU aggregation enable/disable
> nl80211: Add netlink attribute to enable/disable RTS_CTS
> nl80211: Add netlink attribute to configure TID specific tx rate
> mac80211: Add api to support configuring TID specific configuration
> ath10k: Add wmi command support for station specific TID config
> ath10k: Add new api to support TID specific configuration
> ath10k: Add extended TID configuration support
>
> v3:
> * Modified "nl80211: Add netlink attribute to configure TID specific tx rate" patch
> to accept multiple TX rate configuration at a time.
> * Modified noack and ampdu variable data type to int in
> "mac80211: Add api to support configuring TID specific configuration" patch to store
> default configuration.
> * Modified "ath10k: Add new api to support TID specific configuration" patch to handle
> default values for noack and ampdu. And added sta pointer sanity check in
> ath10k_mac_tid_bitrate_config function.
> * Fixed "ath10k: Add extended TID configuration support" wmi command parameters
> assigned part.
>
> v2:
> * Added support to accept multiple TID configuration
> * Added support to configure TX rate and RTSCTS control
