[net-next PATCH 4/5] flow_dissector: Use same pointer for IPv4 and IPv6 addresses

[Alexander Duyck <aduyck@mirantis.com>]

The IPv6 parsing was using a local pointer when it could use the same
pointer as the IPv4 portion of the code since the key_addrs can support
both IPv4 and IPv6 as it is just a pointer.
