Trying to adapt Olaf's vif MTU patch for EL5.6's 2.6.18-238.9 kernel

[Digimer <linux@alteeve.com>]

Hi all,

  With a *lot* of help from Pasi yesterday, I was trying to get Olaf's
vif MTU patch
(http://lists.xensource.com/archives/html/xen-devel/2011-02/msg00352.html)
applied against the most recent EL5.6 (RHEL 5.6/CentOS 5.6) kernel
version 2.6.18-238.9.

  The patch as-is didn't apply cleanly, as there seemed to be a line
shift issue with common.h and xenbus.c. I manually added the lines and
created a new patch, but I screwed something up and it fails to compile.
I should note that I am /not/ a C programmer. :)

  Here is adapted patch:

  And here is the compile output with errors:

  I applied it as Patch 28000. Here is the diff on the kernel-2.6.spec
(http://centos.alteeve.com/5.6/updates/SRPMS/kernel-2.6.18-238.9.1.el5.src.rpm).

  Any advice/help/clue-stick whacking would be much appreciated!
