+The functions were originally introduced to handle
+.Tn PCI
+bus master devices, which assumed little endian byte order in
+.Tn DMA
+transfers, even on big endian systems.
There are a few PCI bus master devices that are big endian aware
(epic(4) for example), so I don't think it's appropriate to add
commas around the which clause.
