Oops, in my previous mail I forgot to give an explanation for the
following lines, which are actualy a bug fix and not really part of the
patch:

Bootfile name may be offered either in the bootp header (file field),
or, when "option overload" (=option 52) is set, in the variable dhcp
options field as option 67.

So previously ipconfig incorrectly didn't accept option 67 as a bootfile
name.

This is still true (=incorrect) for the sname field in the bootp header,
which may also be offered as option 66, but sname is not currently used
anywhere in the code, so I didn't insert similar code for "case 66:".


Kind regards,
