|

|
|
* The firmware will allocate two events.
|
||
|
|
* Valid for BSS_STA and P2P_STA.
|
||
|
|
* * A rather short event that can't be fragmented and with a very
|
||
|
|
* high priority. If every goes well (99% of the cases) the
|
||
|
|
* association should complete within this first event. During
|
||
|
|
* that event, no other activity will happen in the firmware,
|
||
|
|
* which is why it can't be too long.
|
||
|
|
* The length of this event is hard-coded in the firmware: 300TUs.
|
||
|
|
* * Another event which can be much longer (it's duration is
|
||
|
|
* configurable by the driver) which has a slightly lower
|
||
|
|
* priority and that can be fragmented allowing other activities
|
||
|
|
* to run while this event is running.
|
||
|
|
* The firmware will automatically remove both events once the driver sets
|
||
|
|
* the BSS MAC as associated. Neither of the events will be removed
|
||
|
|
* for the P2P_STA MAC.
|
||
|
|
* Only the duration is configurable for this protection.
|
||
|
|
* @SESSION_PROTECT_CONF_GO_CLIENT_ASSOC: not used
|

|
|
* @SESSION_PROTECT_CONF_P2P_DEVICE_DISCOV: Schedule the P2P Device to be in
|
||
|
|
* listen mode. Will be fragmented. Valid only on the P2P Device MAC.
|
||
|
|
* Valid only on the P2P Device MAC. The firmware will take into account
|
||
|
|
* the duration, the interval and the repetition count.
|
||
|
|
* @SESSION_PROTECT_CONF_P2P_GO_NEGOTIATION: Schedule the P2P Device to be be
|
||
|
|
* able to run the GO Negotiation. Will not be fragmented and not

|
|
* repetitive. Valid only on the P2P Device MAC. Only the duration will
|
