But I still don't see how I can tell if the incoming path is absolute or
relative.

e.g.
chdir ("/TFTP/somehereville/");
results in "somewhereville/" being passed to tftp_eval_path().

chdir ("somewhereville/");
results in "somewhereville/" being passed to tftp_eval_path().

How can tftp_eval_path() decide which of these is relative and which is
absolute?  They look pretty similar to me :-)

The code now in the driver assumes the path is absolute.
