    net: Add full IPv6 addresses to flow_keys · c3f83241
    Tom Herbert authored
    This patch adds full IPv6 addresses into flow_keys and uses them as
    input to the flow hash function. The implementation supports either
    IPv4 or IPv6 addresses in a union, and selector is used to determine
    how may words to input to jhash2.
    
    We also add flow_get_u32_dst and flow_get_u32_src functions which are
    used to get a u32 representation of the source and destination
    addresses. For IPv6, ipv6_addr_hash is called. These functions retain
    getting the legacy values of src and dst in flow_keys.
    
    With this patch, Ethertype and IP protocol are now included in the
    flow hash input.
