Modified Files:
        src/sys/dev/pci: if_tl.c

Log Message:
The Set Engineering GIO board for sgimips (IP22) sits behind a special
bridge that precludes the ThunderLAN's DMA engine from performing segment
transfers across page boundaries. Add logic under #ifdef TL_SETENG_GFE to
split up these segment transfers appropriately.

- This #ifdef should be replaced by prop_dictionary
  (see dev/pci/ahc_pci.c and sgimips/autoconf.c)
- I think this boundary restriction could be handled by an arg of
  bus_dmamap_create(9) and you don't have to split segments manually

Ah, excellent. This is much better -- I'll make the appropriate changes right now!
