[PATCH 00/12] mac80211: add multiple bssid support

[John Crispin]

Multiple bssid allows us to share a single beacon amongst several VAPs.
This essentially safes airtime. This feature is achieved by adding an
additional IE to the transmitting VAPs beacon. This new IE contains
the additional SSIDs and their non-inheritance information.

This series is still missing handling for TIM, which will be sent in a
follow-up series.

[PATCH 01/12] nl80211: add basic multiple bssid support

[John Crispin]

This patch adds support for passing the multiple bssid config to the
kernel when adding an interface. A bss can be legacy, transmitting or
non-transmitting. A non-transmitting BSSID will have a parent interface,
which needs to be transmitting.

Are you expecting BSSID or ifindex in multi_bssid_parent? If it is 
ifindex, it can be 0. no

[PATCH 02/12] nl80211: add attributes for multiple bssid related settings

[John Crispin]

When we start a multiple bssid AP we need to pass the index and number of
peers aswell to the kernel. This info needs to be propagated to the
driver.

[PATCH 02/12] nl80211: add attributes for multiple bssid related settings

[John Crispin]

When we start a multiple bssid AP we need to pass the index and number of
peers aswell to the kernel. This info needs to be propagated to the
driver.

John,

Does the count include transmitting and non-transmitting APs? Or just 
child-node counts.
Are you expecting start_ap() for all non-trasmitting AP as well? Hope 
this count can be
set only for parent AP?

[PATCH 03/12] nl80211: add attributes to set beacon transmit mode

[John Crispin]

Beacons on a radio can be sent out in burst (back to back) or staggered
(equally spread out over time) mode. This patch adds the required nl80211
attributes allowing us to configure this from userland.

[PATCH 04/12] mac80211: add multiple bssid support

[John Crispin]

When bringing up multi bssid APs we need to track the parent-child relation
of non-transmitting and transmitting VAPs.

The patch makes sure that
* a parent can not be deleted while it has children
* a parent can only be opened when all children are open
* a childs parent needs to exist when the child is added
* a child can only be closed when its parent is already closed

This patch ensures the above by using a linked list to track the relations.

[PATCH 05/12] mac80211: add multiple bssid IE parsing

[John Crispin]

Drivers might need to know the offset and length of the IE. Add parsing
code and propagate the values to the driver using the mutable struct.

[PATCH 05/12] mac80211: add multiple bssid IE parsing

[John Crispin]

Drivers might need to know the offset and length of the IE. Add parsing
code and propagate the values to the driver using the mutable struct.

[PATCH 08/12] ath11k: pass multiple bssid info to FW when a new vdev is created

[John Crispin]

When we use multiple bssid the FW needs to know if the bssid is
non/transmitting and what the vdev_id of the parent is. This patch adds
the required code to achieve this.

[PATCH 08/12] ath11k: pass multiple bssid info to FW when a new vdev is created

[John Crispin]

When we use multiple bssid the FW needs to know if the bssid is
non/transmitting and what the vdev_id of the parent is. This patch adds
the required code to achieve this.

[PATCH 09/12] ath11k: add a struct to pass parameters into ath11k_wmi_vdev_up

[John Crispin]

When setting up a multiple bssid we need to pass additional parameters to
the FW. Doing this as individual parameters would make the call signature
very long. Use an intermediate struct instead and adjust all callees to
make use of it.

[PATCH 10/12] ath11k: add the multiple bssid IE offset to the beacon template

[John Crispin]

The FW needs to know the offset of the multi bssid IE. Add this value to
the WMI TLV.

Hi,
looks like i folded the fix patch into the wrong patch. these values get 
added in this same patchset. Johannes commented on the nl80211 part 
already and i will send out a V2 this week.

Not sure how you got the above values? Please confirm.

#define VDEV_FLAGS_NON_MBSSID_AP      0x00000001   /* legacy AP */
#define VDEV_FLAGS_TRANSMIT_AP        0x00000002   /* indicate if this 
vdev is transmitting AP */

#define VDEV_FLAGS_EMA_MODE           0x00000008   /* vdev is EMA and 
supports multiple beacon profiles. */
