3c509: Fix resume from hibernation for PnP mode.
From: Ondrej Zary <linux@rainbow-software.org> last year, I posted a patch which fixed hibernation on 3c509 cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I stopped using hibernation (as it did not work with my new IT8212 RAID controller). Now I fixed it and noticed that 3c509 does not wake up properly anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig down/up makes the card work again in PnP mode. However, in ISA mode, ifconfig up ends with "No such device" error. Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only some statistics-related change. So the cause of the problem must be somewhere else. This patch makes the resume work in PnP mode, but it's still not enough for ISA mode. Signed-off-by: David S. Miller <davem@davemloft.net>
