Hi all,

I am running Netmap with "intel 10G 82598EB" card in promiscuous mode.
While capturing packets via Netmap the driver is stripping off Vlan =
tags.=20
I tested my setup, I am able to see Vlan tags when the same card is in =
promiscuous=20
mode without Netmap.

This maybe due to the netmap related changes to the device driver code.
But I don't know much about drivers. I would appreciate any help or =
pointer
regarding this.

Thanks,
Htandra.
