Just as the name I40E_TX_OFFLOAD_NOTSUP_MASK indicates, it should be the mask of unsupported features (either not in PKT_TX_OFFLOAD_MASK or in I40E_TX_OFFLOAD_MASK), however, xor will not get desired result here, assume bit 0 of PKT_TX_OFFLOAD_MASK and I40E_TX_OFFLOAD_MAKS are 0 which means corresponding feature is not supported in both sides, then we get value of bit 0 of I40E_TX_OFFLOAD_NOTSUP_MASK which is 0 via xor, it implies that it is supported which doesn't meet our expectation. Correct it by a NOT-AND operation. Fixes: 3f33e643e5c6 ("net/i40e: add Tx preparation") Cc: stable@dpdk.org Signed-off-by: Xiaolong Ye <xiaolong.ye@intel.com> Acked-by: Qi Zhang <qi.z.zhang@intel.com>
