This breaks:

src/sys/dev/pci/if_tl.c: In function 'tl_init':
src/sys/dev/pci/if_tl.c:660: error: 'usetd' undeclared (first use in this function)
src/sys/dev/pci/if_tl.c:660: error: (Each undeclared identifier is reported only once
src/sys/dev/pci/if_tl.c:660: error: for each function it appears in.)
src/sys/dev/pci/if_tl.c:660: error: 'PROP_TYPE_INTEGER' undeclared (first use in this function)

I can't figure out where 'usetd' comes from; it's not referenced in if_tl.c
elsewhere.
