net: Add full IPv6 addresses to flow_keys
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.
