[PATCH v3 0/7] v3: ath11k: MBSSID and EMA support in AP mode.

[PATCH v3 0/7] v3: ath11k: MBSSID and EMA support in AP mode.

[Aloka Dixit]

Add support for multiple BSSID (MBSSID) and enhanced multi-BSSID
advertisements (EMA) features in AP mode.
Set the extended capabilities, WMI resource config parameters to
advertise the driver support.
Set the MBSSID profile parameter such as BSSID index, total BSS count.
Retrieve and propagate the EMA beacon templates to firmware.
Set the vif security parameters for the non-transmitting profiles.

This is the next version for the following series:
https://patchwork.kernel.org/project/linux-wireless/list/?series=695229&state=%2A&archive=both
- Added 'wifi: ' to the title in all patches.
- Patch [v2,01/10] mac80211: generate EMA beacons in AP mode is
merged hence no dependency.
- Patch [v2,05/10] ath11k: create a structure for WMI vdev up parameters
is deleted from this version as it was not adding much value.
- Patch [v2,09/10] ath11k: EMA beacon support is split into two patches,
  6/7 and 7/7 to make the EMA additions clearer.
- Patch [v2,10/10] ath11k: configure WPA and RSN parameters for
  nontransmitting interface is incorporated in 6/7 as it is required
  to complete the MBSSID related support.

[PATCH v3 1/7] wifi: ath11k: driver settings for MBSSID and EMA

[Aloka Dixit]

Advertise the driver support for multiple BSSID (MBSSID) and
enhanced multi-BSSID advertisements (EMA) by setting extended
capabilities.

Configure mbssid_max_interfaces and ema_max_profile_periodicity
fields in structure wiphy which are used to advertise maximum number
of interfaces and profile periodicity supported by the driver.

Add new WMI fields to configure maximum vdev count supported for
MBSSID and profile periodicity in case of EMA.
Setting WMI_RSRC_CFG_FLAG2_CALC_NEXT_DTIM_COUNT_SET flag
indicates that the firmware should track and update the DTIM counts
for each non-transmitted profile.

[PATCH v3 2/7] wifi: ath11k: MBSSID configuration during vdev create/start

[Aloka Dixit]

Configure multiple BSSID flags and index of the transmitting interface
in vdev create/start commands depending on the service bit
WMI_TLV_SERVICE_MBSS_PARAM_IN_VDEV_START_SUPPORT.

[PATCH v3 3/7] wifi: ath11k: rename MBSSID fields in wmi_vdev_up_cmd

[Aloka Dixit]

Rename trans_bssid to tx_vdev_bssid to make it similar to vdev_bssid.

Rename profile_num to nontx_profile_cnt, and profile_idx to
nontx_profile_idx which makes it clear that these store configurations
related to MBSSID non-transmitting profiles.

Tested-on : IPQ8074 hw2.0 AHB WLAN.HK.2.7.0.1-01744-QCAHKSWPL_SILICONZ-1
Signed-off-by: Aloka Dixit <quic_alokad@quicinc.com>
---
v3: Added 'nontx_' before the renamed members compared to v2.
v2: New patch in this version. Code moved from patch 5/9 in v1.

v3: No logical changes from v2. But '[v2,05/10] ath11k: create a
    structure for WMI vdev up parameters' is deleted in this
    version hence the function prototype is diffferent.

v2: Additions in struct vdev_up_params moved from patch 5/9 in
    v1 to this patch.

[PATCH v3 5/7] wifi: ath11k: refactor vif parameter configurations

[Aloka Dixit]

Security parameters for each non-transmitting profile can be
different when MBSSID is enabled and this information is included
in the MBSSID element in the Beacon frame. Current implementation
to set rsnie_present and wpaie_present does not parse this element
hence it applies only to the transmitting interface.

Move the code to a separate function to make additions for
non-transmitting interfaces cleaner.

Signed-off-by: Aloka Dixit <quic_alokad@quicinc.com>
---
v3: Renamed ath11k_mac_setup_bcn_tmpl_vif_params(0 as
    ath11k_mac_set_vif_params() as the parameters are not actually
    set in the Beacon frame. MLO link ID change is not required
    anymore.

v2: Changed calls to mac80211 APIs to include MLO link ID.

[PATCH v3 6/7] wifi: ath11k: MBSSID beacon support

[Aloka Dixit]

- Split ath11k_mac_setup_bcn_tmpl() to move the beacon retrieval and
  WMI command to a new function, ath11k_mac_setup_bcn_tmpl_legacy().
  In the original function add checks to use the transmitting interface
  when MBSSID is enabled.
- Set rsnie_present and wpaie_present fields for the non-transmitting
  interfaces when MBSSID is enabled.

v3: Squashed some hunks from patches 09/10 and 10/10 from v2 to create
    this which logically adds support for MBSSID, beacon related
    as well as vif parameters for non-transmitting profiles.
    Renamed ath11k_mac_setup_bcn_tmpl_nontx_vif_rsnie() as
    ath11k_mac_setup_nontx_vif_rsnie() as this function does
    not set anything in the beacon template.
v2: Rebase only.

Thank you.

I saw the warning but couldn't decide between adding a new pointer 
variable and letting 2 extra characters for just one assignment.

What are your thoughts on changing the scripts to allow up to 100?
Although nl80211 and mac80211 scripts also don't allow that long currently.

My scripts will fail loudly if any of the ath*0k-check scripts have
warnings, so just like with compiler warnings I have a zero warnings
policy :) It would become a mess otherwise to know which warnings are
new and which are old.

Yeah, the checkpatch default is 100 right now and I have understood that
what Linus prefers. I'm just worried that increasing the max to 100
makes our code even more convoluted, it's a challenge as is.
