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_TID_ATTR_CONFIG_NOACK attribute.
Data TID value for this configuration will be passed through
NL80211_TID_ATTR_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

Argument 'info' is missing here from parse_tid_conf. IIUC, appropriate
fixup is included into patch #5. So it looks like rebase issue. But it
makes sense to fix it since this issue makes the patch set
non-bisectable.
My bad. Yes, it is missed in the rebase. I will fix that.
Thanks,
Tamizh.
