Hi, Navneet
I'm sorry for I have no idea about the NIC i540. Are you talking about X540?
If X540, I guess you can't classify on the MAC-ADDRESS to different queue by ethertype filter. Because in the X540 datasheet the ethertype filter is described as below:
" 7.1.2.3 L2 Ethertype Filters
These filters identify packets by their L2 Ethertype, 802.1Q user priority and optionally
assign them to a receive queue."
So the mac_address is not the filter's input.
Thanks
Jingjing
