New PRM defined new field OUT_IPV6_TRAFFIC_CLASS for IPv6 which will be
used by both IPv6 ECN and DSCP. To apply the new ID and keep backward
compatibility with different RDMA core and FW releases, 1) detect the
support of the new ID in RDMA core and FW. 2) apply the new ID if possible
otherwise, keep using the old ID.
