MFC: r201932
- 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.
