From 013beb7bc5036bf627fce3707a7a83344ffa05aa Mon Sep 17 00:00:00 2001

Subject: [PATCH 41/60] add support to offload TWT setup request handling to
the Firmware
With "TWT_SETUP" control sock cmd interface currently available in the
wpa_supplicant, it is currently possible to generate the TWT Setup Action
frame with the desired TWT session params like SP, SI, TWT Setup cmd type,
Flow ID, Trigger/Non-Trigger based, Un-Announced/Announced session types,
etc, without informing the TWT state machine in the Firmware.
Now introduce a new TWT Offload code path and then when the TWT Setup is
triggerd either through the "$ wpa_cli twt_setup" or directly though the
control sock cmd "TWT_SETUP", construct a Vendor nl80211 cmd of type "TWT"
and pass it to the driver if it supports this new vendor cmd. The driver
then could inform the TWT module in the firmware through the corresponding
IOVAR to initiate a TWT Setup request while updating the TWT negotiation
handshake state machine as needed.
Upstream-Status: Inappropriate [DEY specific]
