Hello Mikael, " For me, it seems these 802.11 broadcast/multicast ACK functions should be "mandatory" to implement if the device wants to support IPv4 and IPv6 networks.
How do we achieve this?" There are two routes to "mandatory". The standard can indicate something is mandatory if you support a particular feature. The second is certification. This is the not-so-simple task of persuading a sufficient number of WiFi-Alliance members that it is in their economic interest to support the feature that a certification program can be created. Even, given a certification, the market will still decide whether that is relevant or not.

Thanks for the summary, it seems correct. It might not need new 802.11 standards, but we still have an operational problem in that it seems some of these standards are not universally implemented by 802.11 based device vendors. IETF standards generally assume that multicast and unicast are delivered with a similar level of packetloss (which is low). Not all 802.11 implementations have the multicast ACK mechanism implemented, thus it would seem that multicast will be less likely to get delivered to the recipient over these 802.11 implementations. For me, it seems these 802.11 broadcast/multicast ACK functions should be "mandatory" to implement if the device wants to support IPv4 and IPv6 networks.
