Can you probably > clarify? The restriction is that: rte_bpf_eth_tx_elf_load() can not be be used with RTE_ETH_TX_OFFLOAD_MT_LOCKFREE because if that offload is set, application is allowed to share a single transmit queue across multiple lcore. It would be better if the attempts to load on such a device failed. But in the is not enough because at least in theory a user could enable the offload later by reconfiguring the device.
