Currently the on disk format used by XFS on Linux is not compatible with that
used on Irix. Work is in progress to add the byte swapping work to support the
Irix format. So:

MIPS format is the Irix on disk format
Native is whatever format the local cpu supports (no byte swapping)
Multi is support for runtime switchable support

The current thinking is the get the MIPs format working on Intel boxes and
measure the overhead. If it is low enough then all the other formats go away
and we stick with the single format. If the overhead is significant we probably
support multiple formats, but I doubt that multi (run time detection and
switching) will be a viable option.
