MFp4:
USB CORE: busdma improvement
For single segment allocations the boundary field
of the BUSDMA tag should be zero. Currently all
single segment allocations are less than or equal
to 4096 bytes, so the limit does not kick in. If
any single segment USB allocations would be greater
than 4K, then it would be a problem.
