Subject: [PATCH] hostapd: Fix lowest association ID with multiple BSSID element
|
|
|
|
Association ID space is shared when multiple BSSID element is included
|
|
in beacons.
|
|
|
|
As per IEEE P802.11ax/D6.0, 11.1.3.8.5 Traffic advertisement in a
|
|
multiple BSSID set, the lowest association ID to be assigned to non-AP
|
|
station should be 2^n, where n is the maximum BSSID indicator of the
|
|
multiple BSSID set.
|
|
Example, if the set has 6 BSSes, the lowest association ID will be 8.
|
|
|
|
This patch sets the correct value which was incorrectly set to the number
|
|
BSSes in the multiple BSSID set.
