RSS Hash Function
The 82574’s hash function follows Microsoft’s* definition. A single hash function is
defined with five variations for the following cases:
• TcpIPv4 - The 82574 parses the packet to identify an IPv4 packet containing a TCP
• IPv4 - The 82574 parses the packet to identify an IPv4 packet. If the packet is not
• TcpIPv6 - The 82574 parses the packet to identify an IPv6 packet containing a TCP
segment per the following criteria. If the packet is not an IPv4 packet containing a
TCP segment, receive-side-scaling is not done for the packet.
an IPv4 packet, receive-side-scaling is not done for the packet.
segment per the following criteria. If the packet is not an IPv6 packet containing a
TCP segment, receive-side-scaling is not done for the packet. Extension headers
should be parsed for a Home-Address-Option field (for source address) or the
Routing-Header-Type-2 field (for destination address).
