  SVN rev 180263 on 2008-07-04 20:53:41Z by jhb
  
  Make sbni(4) MPSAFE:
  - Add a mutex to the softc and use it to protect the softc and device
    hardware.
  - Setup interrupt handler after attaching device to network stack.
  - Use device_set_desc() rather than device_quiet() plus a manual printf
    that simulates the normal probe printf.
  - Axe next_sbni_unit and instead just leave room for two sbni devices for
    each bus attachment.
  - Don't bzero the already-zero'd softc.
  - Add a detach method to the PCI driver.
  - Add a lock to protect the list of available devices used to chain
    interrupt handlers for dual port ISA cards.
  - Remove unused watchdog routine.
  - If if_alloc() fails, make sbni_attach() return an error rather than
    panic'ing.
  - Consolidate code to free bus resources into sbni_release_resources().
  - Clear IFF_DRV_RUNNING|OACTIVE in stop() routine instead of in callers.
  - Let ether_ioctl() handle SIOCSIFMTU.
