Message

From: Tamizh chelvam <[e-mail]>

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 (6):
  nl80211: Add NL command to support TID speicific configurations
  nl80211: Add support to configure TID specific retry configuration
  nl80211: Add support to configure TID specific AMPDU configuration
  nl80211: Add support to configure TID specific RTSCTS configuration
  nl80211: Add support to configure TID specific txrate configuration
  mac80211: Add api to support configuring TID specific configuration
