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.
