I made minor changes to the patch and committed in revision 351.

The first change I made was to add version checking between user-mode
and kernel-mode, so that changes in the IOCTL interface would not
result in undetermined behavior.  This was done in revision 350.

I moved the enforcement of GET to the proxy, so that the interface
can't be abused.  Other than that, I changed formatting a little.

I applied only the IBAL portions of this - the MTHCA edits seemed unrelated.
I didn't apply the vstat changes because all I ever see is zeros
coming out for the port counters.  Are these supposed to work over the
MT23108 driver?  There shouldn't be anything HCA driver specific here,
so I'm puzzled by the results I'm seeing.

Please let me know if I screwed something up when applying the patch
that causes the results to always be zero.  I'll let you apply the
vstat changes.

Thanks,

- Fab
