Does it have to be ^2? In the iWARP spec development, we envisioned
the possibility of arbitrary page sizes. I don't recall any such dependency
in the protocol architecture.

Storage has been known to adopt non ^2 blocks, for instance including
block checksums in sectors, etc. If transferred, these will become quite
inefficient on ^2 hardware.
