Re: [dpdk-dev] flow_director_filter error!!

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
