Hi All

     there is

 

        /* Controller has hardware checksum support */

          #define FEC_QUIRK_HAS_CSUM                (1 << 5)

     in linux 3.10.17/53


     and

         .name = "imx6q-fec",

          .driver_data = FEC_QUIRK_ENET_MAC | FEC_QUIRK_HAS_GBIT |

                       FEC_QUIRK_HAS_BUFDESC_EX | FEC_QUIRK_HAS_CSUM |

                        FEC_QUIRK_HAS_VLAN | FEC_QUIRK_ERR006358 |

                        FEC_QUIRK_BUG_WAITMODE,

that is the FEC can do hardware checksum,but it does not work!

which register control this ? and How can I set the register ?

thanks.
