Redo the interupt handling of sky2 driver based on the IRQ mangement documentation. All interrupts are handled by the device0 NAPI poll routine. Don't need to adjust interrupt mask in IRQ context, done only when changing device under RTNL. Therefore don't need hwlock anymore.

Remove wake on lan support for now. It doesn't work right, and I don't have a machine with working suspend/resume to test or fix it. It will be re-enabled later. Signed-off-by: NStephen Hemminger <shemminger@osdl.org> Signed-off-by: NJeff Garzik <jeff@garzik.org>

The Yukon EC/rev0 (A1) chipset requires a bunch of workarounds. I copied these from sk98lin. But since they never got tested and add more cruft to the code; any attempt at using driver as is on this version will probably fail. It looks like this was a early engineering sample chip revision, if it ever shows up on a real system. Produce an error message.

Turn on truncation to prevent getting choked by frames larger than expected. Without this fix, driver hangs after receiving an oversize packet. Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

Avoid premature transmit ring full conditions. Force a transmit status interrupt if transmit ring gets nearly full and after a TSO send. Allow more entries in transmit ring to be used if dma_addr is 32 bits Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

Remove Message Signaled Interrupt support (for 2.6.16). MSI is inherently edge-triggered and that is incompatiable (without more work) with NAPI. In future, will replace with smarter lockless-IRQ handling like tg3.c Signed-off-by: NStephen Hemminger <shemminger@osdl.org> Signed-off-by: NJeff Garzik <jeff@garzik.org>

Need to avoid race in updating IRQ mask. This can probably be replaced smarter use of the interrupt control registers (if/when chipset docs are available). Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

To avoid problems with PCI config access without ACPI (or busted ACPI tables), use the device's window into PCI config space. I know this probably will upset the purists, but I would rather have users than ACPI testers. It also generates less code. Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

Need to force a transmit coalesce timer restart after processing transmit packets. Otherwise, can get transmit status after last update and chip doesn't send the next one. Can go with the chip defaults for coalescing timers, except for Tx timer which needs to be bigger. Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

Don't allow coalescing values to be bigger than the transmit ring. Since if you set them that big, the interrupt never happens and driver livelocks. Signed-off-by: NStephen Hemminger <shemminger@osdl.org>

Users report problems w/ auto-negotiation disabled and the link set to 100/Half or 10/Half. Problems range from poor performance to no link at all. The current sky2 code does not set things properly on link up if autonegotiation is disabled. Plus it does not contemplate a 10Mbit setting at all. This patch corrects that. Signed-off-by: NJohn W.

Using the sky2 driver with bonding can result in oopses related to reinitializing the PHY when the MAC address is changed (which bonding is wont to do). This patch changes sky2_set_mac_address to take less drastic measures. This is analagous to the skge patch here: http://lkml.org/lkml/2005/9/29/399 which fixed the issue here: http://bugzilla.kernel.org/show_bug.cgi?id=5271Signed-off-by: NJohn W.
