Correctly handle the conversion from virtual to physical addresses. The
problem was basically (for offset > 4096): vtophys(addr) + offset != vtophys(addr + offset) Also, use TD's with a maximum size of 4k instead of 8kb for OHCI controllers. This problem occurs in drivers that use large transfer sizes: umass, host2host and ethernet with jumbo frames.
