Utilising QoS (802.1p) in a NDIS driver

Hi

We’re trying to implement QoS, where our Ethernet board supports 802.1p and
our NDIS driver has been changed to support this option. The driver uses
NDIS_PER_PACKET_INFO_FROM_PACKET(_Packet, Ieee8021pPriority) to retrieve the
priority from the packet.
The problem is that the retrieved priority is always 0, except if “pathping
-T x.x.x.x” is issued. If “pathping -T x.x.x.x” is issued, one of the
packets has priority set to 7.
It seems like this priority field is not very useful. Does anyone know how
to cause this priority field to be set to a nonzero value?

Cheers

Mark Riley

you have to make a protocol that makes use of this field, one way to test
this is to run ndtest from the HCT test suite.
