In DPDK this is ETH_RSS_L2_PAYLOAD.
The ixgbe driver does not list this is a supported offload type:
#define IXGBE_RSS_OFFLOAD_ALL ( \
ETH_RSS_IPV4 | \
ETH_RSS_NONFRAG_IPV4_TCP | \
ETH_RSS_NONFRAG_IPV4_UDP | \
ETH_RSS_IPV6 | \
ETH_RSS_NONFRAG_IPV6_TCP | \
ETH_RSS_NONFRAG_IPV6_UDP | \
ETH_RSS_IPV6_EX | \
ETH_RSS_IPV6_TCP_EX | \
ETH_RSS_IPV6_UDP_EX)
The Linux driver does not appear to support this either.
