Mike,
I wish I could tell you that it would, but since I have not seen the       
problem (and actually have been out of VLSI circles for a couple years) I  
can't say that it will.  However, if you did not patch the header file     
that Christos mentioned (net.h) you could certainly be getting all sorts   
of problems.  The index into the array is defined as char.  If the offset  
has the 7th bit as one, it is treated as a NEGATIVE offset.  This will     
screw you to no end.  It is imperative that you make it an unsigned short  
or something like that.
