Then I would suggest sending the patch for review and inclusion in the
kernel. Documentation/SubmittingPatches and Documentation/SubmittingDrivers
in the kernel source tree may be helpful.
However I would still probably think that IPoIB for non-IB networks is
unnecessary complexity -- the mismatch of IB and traditional ethernet/IP
semantics makes even IPoIB a bit of a problem for some apps, and then
layering a not-IB network on top of that is probably not a good idea.
