You need to do more than just advertise the capability to get the driver
to actually work right.

AI explanation:

Error: VXLAN TSO is advertised unconditionally but the underlying hardware
feature is not. The patch adds RTE_ETH_TX_OFFLOAD_VXLAN_TNL_TSO to the
unconditional tx_offload_capa assignment in hinic3_dev_infos_get(), but
the Tx path in drivers/net/hinic3/hinic3_tx.c:306-313 rejects every VXLAN
tunnel mbuf when the hardware does not have NIC_F_VXLAN_OFFLOAD:
