mbuf is marked for delayed checksums, then additionally mark the
packet as having it's checksums computed. This allows us to bypass

useful for REX-5580 series (for PC-AT). But they are included in
`#ifdef PC98' to avoid warnings by unused static functions. If you
try to support REX-5580, please be aware of these functions.

supports indirect pio and bus_at386.h is identical to old bus.h, there
is no functional change in PC-AT's kernels. That is, it cannot cause
performance loss.
