To: kvalo, johannes; +Cc: linux-wireless, Avraham Stern, Gregory Greenman
From: Avraham Stern <avraham.stern@intel.com>
For TM/FTM frames, report the hardware timestamps reported by the
fw as part of the RX/TX status. Since the fw reports the timestamps
in a dedicated notification (and not as part of the RX/TX status),
hold the frame until the fw timestamps notification is received.
Timestamping is enabled when a station is connected and disabled
when disconnected. For AP interface, only the first station will
have timestamping enabled since the fw only supports timestamping
for one peer.

Non-QOS nullfunc frames should be sent on MGMT queue similarly to
the QOS nullfunc frames. It means that the corresponding TID should
remain IWL_MAX_TID_COUNT. Make the condition more strict, so the TID
won't be changed to IWL_TID_NON_QOS.

Instead of calculating the offset to the 802.11 header based on radiotap
bits and length, shorten the code path by always setting the MAC header
in the skb and using skb_mac_header().

Read the STEP equalizer parameters from the BIOS during init
and transfer it to the firmware.
This table provides values to configure an equalizer at the transmitter
that can be used to compensate for PCB channel attenuation.

The rfkill() callback was invoked with wrong parameters.
It was missed since MEI is defined now as depending on BROKEN.
Fix that.
Fixes: d288067ede4b ("wifi: iwlwifi: mei: avoid blocking sap messages handling due to rtnl lock")
Fixes: 5aa7ce31bd84 ("wifi: iwlwifi: mei: make sure ownership confirmed message is sent")
