Exactly.  6pack.c and mkiss are derived from slip.c which being an uncommon
protocol these days is also suffering from bitrot.  Many of the past
updates for 6pack.c and mkiss were following the path set by slip.c ...

Admitedly, there are few good examples for how to write a line discipline
like slip.  PPP is reasonably well written but a way too complex protocol
to be a good example, n_tty.c is too simple to be useful and the Linux tty
code is hard to read.  So in short, there's a lack of good and simple
examples, maybe one reason of several why this code was suffering from
bitrot so badly ...

Well, you didn't say how it failed so I can only guess ...

Well, the command is right asssuming your working directory was the root
directory of the kernel source tree like in this example:

  cd /usr/src/linux-2.6.4
  patch -p0 < 2.6.3-6pack-6.diff

Just in case if the patch file got corrupted, ftp it from ftp.linux-mips.net
in /pub/ham/6pack/.
