A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

The resume bug was caused not by an early interrupt but because the idle timeout was not being stopped on suspend. Also disable hardware IRQ's on suspend. Will need to revisit this with hotplug?

This fixes two independent problems: it would not save the PCI state on suspend (and thus try to resume a nonexistent state on resume), and while shut off, if an interrupt happened on the same shared irq, the irq handler would react very badly to the interrupt status being an invalid all-ones state.

If both ports are receiving on the SysKonnect dual port cards, then it appears the bus interface unit can give an interrupt status for frame before DMA has completed. This leads to bogus frames and general confusion. This is why receive checksumming is also messed up on dual port cards. A workaround for the out of order receive problem is to eliminating split transactions on PCI-X. This version is based of the current linux-2.6.git including earlier patch to disable dual ports.

When both ports are receiving simultaneously, the receive logic gets confused and may pass up a packet before it is full. This causes hangs, and IP will see lots of garbage packets. There is even the potential for data corruption if a later arriving packet DMA's into freed memory. It looks like a hardware bug because status arrives for a packet but no data is there. Until this bug is worked out, block the user from bringing up both ports at once. Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

Need to make the edge-triggered workaround timer faster to get marginally better peformance. The test_and_set_bit in schedule_prep() acts as a barrier already. Make it a module parameter so that laptops who are concerned about power can set it to 0; and user's stuck with broken BIOS's can turn the driver into pure polling.
