If anyone has any objections, please let me know. ------------------ From: Felix Fietkau commit 5289976ad887deb07c76df7eecf553c264aeebed upstream. If the first virtual interface is a station (or an AP with beacons temporarily disabled), the beacon of the second interface needs to occupy hardware beacon slot 0. For some reason the beacon index was incorrectly masked with the virtual interface beacon mask, which prevents the secondary interface from sending beacons unless the first one also does.
