The 802.11 wireless Vendor Specific Microsof/WME tag - type 2, subtype 0 (and
2, subtype 1), contain a Qos Info field as specified in the WMM PowerSave
standard.
Currently this field is not decoded, just displayed as a decimal number.
For example see frames 3, 19 and 21 in the attachment. Look under 802.11
Wireless LAN Management frame/Tagged Parameters/Tag:Vendor Specific: Microsof:
WME.
I have an enhancement which correctly decodes this field. The enhancement has
been tested under windows xp, Fedora 14 and Ubuntu builds.
