Subject: [PATCH 0/9] MBSSID and EMA support in AP mode

- Changes in MAC80211 add support for enhanced multiple BSSID (EMA AP).
This patch is the next version for the following series:
https://patchwork.kernel.org/project/linux-wireless/list/?series=558285&state=%2A&archive=both
The changes are now rebased on top of wireless-testing tree which
includes this series:
https://patchwork.kernel.org/project/linux-wireless/list/?series=617531&state=%2A&archive=both

- Patches for ath11k split the changes from following patch in
logical separate patches:
https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
And also use the latest API changes in MAC80211 which were different
at the time of V6.

Aloka Dixit (9):
mac80211: generate EMA beacons in AP mode
ath11k: add WMI resource config for EMA
ath11k: set MBSSID and EMA driver capabilities
ath11k: MBSSID configuration during vdev create/start
ath11k: create a structure for WMI vdev up parameters
ath11k: configure MBSSID device parameters
ath11k: move vif parameter setting in a different function
ath11k: EMA beacon support
ath11k: configure WPA and RSNE parameters for nontransmitting
interface

Subject: [PATCH 1/9] mac80211: generate EMA beacons in AP mode

Add APIs to generate an array of beacons for an EMA AP (enhanced
multiple BSSID advertisements), each including a single MBSSID element.
EMA profile periodicity equals the count of elements.
- ieee80211_beacon_get_template_ema_list() - Generate and return all
EMA beacon templates. Drivers must call ieee80211_beacon_free_ema_list()
to free the memory. No change in the prototype for the existing API,
ieee80211_beacon_get_template(), which should be used for non-EMA AP.
- ieee80211_beacon_get_template_ema_index() - Generate a beacon which
includes the multiple BSSID element at the given index. Drivers can use
this function in a loop until NULL is returned which indicates end of
available MBSSID elements.
- ieee80211_beacon_free_ema_list() - free the memory allocated for the
list of EMA beacon templates.

Add new macro IEEE80211_MBSSID_ELEMS_ALL to be used for basic MBSSID
implementation without EMA.
Modify exsiting functions ieee80211_beacon_get_ap(),
ieee80211_get_mbssid_beacon_len() and ieee80211_beacon_add_mbssid()
to accept a new parameter for EMA index.

Subject: [PATCH 6/9] ath11k: configure MBSSID device parameters

Add new field nontransmitting_vif_count in struct ath11k_vif which
keeps track of non-transmitting interfaces associated with a
transmitting interface when MBSSID is enabled.
The count is decremented when WMI vdev down is invoked and incremented
when WMI vdev up is invoked.
Use this field to set the profile index and total profile count during
WMI vdev up operation.

Subject: [PATCH 8/9] ath11k: EMA beacon support

Add new function ath11k_mac_setup_bcn_tmpl_ema() which invokes the new
API provided by MAC80211 to retrieve EMA beacons. For non EMA APs,
ath11k_mac_setup_bcn_tmpl_legacy() is added which maintains the current
functionality.

imo the above 3 are the only things that should be handled by this
patch. you should only be converting the existing params to the struct:

u32 vdev_id, u32 aid, const u8 *bssid
(why did aid change from u32 in the param list to u16 in the struct?)

the members below should be added later when the associated
functionality is added to the callers

imo the above changes should not be in this patch. if you want to rename
members, do it in a separate patch for that purpose

so to reiterate IMO you should have:
one patch that is just moving the existing params into a struct
one (or more) patch that adds support for the new params
one patch that renames the wmi_vdev_up_cmd members

let each patch do one and only one thing

Not sure where the driver should use this? Why is it defined in the
driver API?

The parameter is a u8 so it cannot be negative anyway ...?

-1 is a strange return value (it means -EPERM but you didn't say it);
maybe use -EINVAL?

A lot of this stuff is now conflicting with MLO work, so also needs a
rebase.

The API here is weird, why not *return* what goes into *ema_beacons?

couple of blank lines would be nice, and maybe check the return value
and WARN_ON() it not being NULL? It should be NULL in this case, I
think?
