But this bit only controls the routing of card functional interrupts, not the CSC interrupts which are used for interrupt probing. A bad side effect of messing with this register in yenta_probe_irq() is that it can lead to irq storms if a card is inserted and already powered by the BIOS. Usage in yenta_sock_init() and yenta_config_init() seem to be fishy as well.

There are a few adapters that are capable of creating devices with this large of a capacity, but now that we have the large fib support in, the management applications will be capable of generating them. The problem is, once they are created, the driver will not be able to access the devices correctly without this patch.

In the rare instances where the adapter, or the motherboard, is misbehaving; driver initialization or shutdown becomes problematic. By introducing a 3 minute timeout on the first interrupt driven command during initialization, or the issuance of the adapter shutdown command during driver unload, we can resolve the lockup problems induced by common (but rare) hardware misbehaviors. The timeout during initialization, should it occur, is accompanied by a message presented to the console and the logs indicating that the user should inspect and resolve problems with interrupt routing.

Associated with this, aac_insert_entry can be removed, SavedIrql can be removed & padding variable can be removed. With the movement of SavedIrql out & replaced with an automatic variable qflags, the locking can be refined somewhat. The sparse warnings did not catch the need for byte swapping in the 'dprintk' debugging print macros, so fixed this up when this code was moved outside of the now refined locking.

MAC_RX_MODE reset must be done before setting up the MAC_MODE register on 5705_PLUS chips or the chip will stop receiving after a while. The MAC_RX_MODE reset is needed to prevent intermittently losing the first receive packet on serdes chips. 2. Skip MAC loopback test on 5780 because of hardware errata. Normal traffic including PHY loopback is not affected by the errata. 3. PHY loopback fails intermittently on 5708S and this is fixed by putting the PHY in loopback mode first before programming the MAC mode register. A MAC_RX_MODE reset is also added. 4. Return -EINVAL in tg3_nway_reset() if device is in TBI mode. Allow nway_reset if 5780S is in parallel detect mode. 5. Add missing PHY IDs in KNOWN_PHY_ID() macro.

While the queue_if_no_path variable is correctly set to 1, the saved_queue_if_no_path gets set to 0. When the device is subsequently made live (resumed), the saved value (0) always overwrites the live value (1) so the option *always* gets turned off. The fix adds a parameter to the queue_if_no_path() function to indicate whether the previous value should be preserved or not - if not, as when the device is being set up, the saved value is set to the new value (1).

This error message is bogus for two reasons. First, it can never occur given that current code takes care to initialize IOC4 in such a way that these "unknown" interrupts could never occur. Second, this code fails to take into account that other drivers can share the IOC4 interrupt mechanism through SA_SHIRQ, and thus this driver is not in-fact "all-knowing". Finally, this error message triggers every time some "unknown" interrupt occurs -- it's not rate limited or repetition limited in any way, thereby effectively denying use of the console device. Given its bogosity in the first place, it's best to just get rid of it entirely.

Test for VIA K8T800 north bridge instead of AMD K8 HyperTransport bridge based on new information from Andi Kleen. The AMD HyperTransport interface is not responsible for PCI transactions and so the re-ordering is more likely done by the VIA north bridge. This code is subject to change if we get more information from AMD or VIA. PCI Express devices are excluded from doing the read flush since all chipsets in the write_reorder list are PCI chipsets.

There is one exception in net/ipv4/route.c which is in fact a pre-existing race condition. I've marked it as such so that we remember to fix it.
