When I fixed this for IPv4 in 1b4a75108d5b, I didn't realise that hash:ip,mac sets also support IPv6 as family, and this is covered by a separate function, hash_ipmac6_kadt(). In hash:ip,mac sets, the first dimension is the IP address, and the second dimension is the MAC address: check the IPSET_DIM_TWO_SRC flag in flags while deciding which MAC address to copy, destination or source. This way, mixing source and destination matches for the two dimensions of ip,mac hash type works as expected, also for IPv6.
