Windows 2008 and 802.1p CoS value


hi,

i aware in order use 802.1p qos cos priority tag, need compatible nic , driver, , need enable 802.1q (vlan) tagging since 802.1p tag in same header @ layer 2.

i know windows 2003 supported setting cos tag (provided driver supported it) through group policy settings, interface deprecated.

i know windows 2008 has new policy-based qos group policy setting allows set dscp value in ip header @ layer 3, somehow magically mapped 802.1p tag value, using undocumented map?

the reason important windows servers plugged layer-2 managed switch not @ layer-3 ip packet , prioritise accordingly, important set layer-2 cos tag.

does windows 2008 support 802.1p? i've been looking last day or , can't seem find answer. can't imagine 802.1p support has been removed windows 2008, there no documentation. appreciated.
