I added the VLAN tag to the raw Ethernet packet and the NDIS driver is able
to send the packets. WireShark shows that sent packets with the proper 802.1q
(VLAN) header. On the receiver side however, the driver the HeaderBufferSize
variable passed (from the miniport) to the NDIS IM driver ReceiveHandler is
12 bytes which is different from the new header size 16 bytes.

if (HeaderBufferSize != sizeof(CAEETHPROT_ETH_HEADER))
{
Status = NDIS_STATUS_NOT_ACCEPTED;
break;
}

I enabled the QoS in the adapter.

How should I correct the received packet header size?


Thanks,

Daniel

I would like to add that on the receiver side Wireshark shows that the VLAN
tag was removed.

Hi,

For incoming packets, the miniport driver removes packet marking if the
802.1Q is enabled. The miniport driver reorders the packets according to
their priority. Is this a priority reordering significant when sending and
receiving even if the NDIS protocol higher driver does not reorder packets?
In other words, Should I enable the 802.1Q to prioritize the traffic in case
of high load?


Thanks,

Daniel
