- In mii_attach(9) just set the driver for a newly added miibus(4) instance

  before calling bus_enumerate_hinted_children(9) (which is the minimum for
  this to work) instead of fully probing it so later on we can just call
  bus_generic_attach(9) on the parent of the miibus(4) instance. The latter
  is necessary in order to work around what seems to be a bzzarre race in
  newbus affecting a few machines since r227687, causing no driver being
  probed for the newly added miibus(4) instance. Presumably this is the
  same race that was the motivation for the work around done in r215348.
  Reported and tested by: yongari
- Revert the removal of a static in r221913 in order to help compilers to
  produce more optimal code.
