Discussion on future 802.1AVB topics
Having an 802.11 BSS act like first class

QoS Maintenance Reports
Action for 802.11aa: Specific details on
802.11k/v traffic stream statistic reports
Making sure 802.11 APs
and STAs know the difference between "multicast" and "group
address" as conditions for routing action ... so that a stream that
has a DA with the "I/G" bit set does NOT necessarily result in a
broadcast transmission (with all the attendant wastage of bandwidth).
