- Add code allowing a network device to only be open and closed once
  by keeping it opened after the first open and closing it via the
  cleanup handler when NETIF_OPEN_CLOSE_ONCE is defined. Note that
  due to the fact that the part of r177108 which reverts r60506 and
  causes the open-close-dance on every file access as the remaining
  problems with powerpc should be sorted out first, in stable/7 the
  only difference in behavior between when NETIF_OPEN_CLOSE_ONCE is
  defined and not currently is that with that macro defined the
  network device is eventually closed before entering the kernel and
  before rebooting.
- Define NETIF_OPEN_CLOSE_ONCE on sparc64 in order to not keep the
  network device opened forever, as at least with some firmware
  versions received packets are DMA'ed to stale memory otherwise.
