Re: [MBONED] draft-ietf-mboned-ieee802-mcast-problems-07 submitted, new WGLC to be initiated

Hi Mike,
This is specific to the ath9k driver. So it's an "optimization" that 
some drivers have. Perhaps it should be:

"The CAB (Content after Beacon) queue is used for beacon-triggered
transmission of buffered multicast frames. If lots of multicast frames
were buffered and this queue fills up, it drowns out all regular
traffic. To limit the damage that buffered traffic can do, some drivers 
limit
the amount of queued multicast data to a fraction of the beacon_interval."

Perhaps with a reference to Felix's patch.

I don't know Felix personally - so I cannot say whether he would want to 
appear as an contributor. Otherwise it sounds fine to me.
