It seems to me these fixup functions are not intended to solve
alignment issues but rather implement device specific framing (such as
when the hardware packs multiple ethernet frames into a single urb)

I sent a patch to the list about 2 weeks ago that added support to
DMA bounce to bounce for misaligned buffers. We have a similar
problem with URB alignment for usbnet on Tegra's HCD:
