Yes, it is supported.
For the configuration, you can refer to the implementation of command set_hash_global_config in testpmd example.

Different requirement may require different configuration.
For example, you'd like to enable RSS on IP packets, you need to set
struct rte_eth_conf to be like
{
.rxmode = {
.mq_mode = ETH_MQ_RX_RSS,
},
.rx_adv_conf = {
.rss_conf = {
.rss_key = NULL,
.rss_hf = ETH_RSS_IP,
},
},
};
This is also to be found in dpdk's examples, such like testpmd and l3fwd.
