[PATCH] libata: add per-dev pio/mwdma/udma_mask
Add per-dev pio/mwdma/udma_mask. All transfer mode limits used to be applied to ap->*_mask which unnecessarily restricted other devices sharing the port. This change will also benefit later EH speed down and hotplug. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
