Traffic shaping won't work for mac80211 #17

Closed dguerri closed 11 years ago

dguerri commented 12 years ago

Traffic shaping currently works only for madwifi-ng.

The main problem for porting L2 traffic shaping to mac80211 is the absence of a "master" device that can be used to shape/control the aggregate traffic from VAPs.

The master device for madwifi-ng is assimilable to a VLAN(s) master interface. Without it, it is impossible to shape aggregated traffic and so it is impossible to implement a "borrowing" mechanism of band from other VAPs when they aren't using all their reserved bandwidth (a cool feature of the HTB queue discipline of Linux TC).

IMO the only shaping we can perform here is very limited with respect to the one we implemented for the madwifi-ng driver.
