How do you use the LWIP hardware checksum

I am using the K66 and would like to use the ENET hardware checksum.

 

I have set:

 

 

    ENET_TFWR |= ENET_TFWR_STRFWD(1);

 

    ENET_TACC |= ENET_TACC_IPCHK(1) | ENET_TACC_PROCHK(1);

 

and defined

 

     CHECKSUM_BY_HARDWARE

 

but the checksum does not work. Is there something else I should do?
