convert Windows NDIS drivers for use with FreeBSD

[jiani1012]

Hi all,
      I am using xp3264-7.7.0.329-whql.zip file from Atheros. 
         #cd /sys/modules/ndis
         #make install
         #cd /sys/modules/if_ndis
         #make install
         #ndiscvt -i netathwx.inf -s athwx.sys -o ndis_driver_data.h       (syntax error)
     When trying to convert the ones athwx.sys and netathwx.inf I am getting the error: 
        > ndiscvt: line 5117: : syntax error. 
        > CONVERSION FAILED 
     same for  netathw.inf athw.sys 
     How to do it?
    Thank you in advance!
