[c-nsp] QoS on WLAN

I've been trying to find some white paper on this, but maybe I'm trying
to do the wrong thing, can't seem to come up with any helpful docs ...

I have a site-to-site WLAN link using two 1242 APs. I'm bridging
multiple VLANs over that link, mainly a data and a VoIP VLAN. So far,
everything is working fine, with a net speed of about 19mbit. In order
to ensure enough bandwidth for the VoIP VLAN, I would like to either
reserve some amount of bandwidth on the bridge for the VoIP VLAN, or set
QoS to prefer transmission of the VoIP packets ... I guess I could shape
the data VLAN to a smaller amount of throughput, but in case of bad
weather, this might still be too much, so QoS should be the cleaner
solution. Is there some simple way to tell the 1242's to tag and prefer
all of the VoIP VLAN?

Tnx, -garry
