2011-03-03ixgbe: rework ixgbe MTA handling to not drop packetsEmil Tantilov
This change modifies the ixgbe drivers so that it will not drop the multicast filters while updating them. Instead it uses an intermediate table to store the filter and then writes that filter to the hardware.

2011-03-03ixgbe: cleanup X540 PHY reset function pointerDon Skidmore
The X540 PHY reset pointer isn't currently used which is a good thing as it wouldn't work as implemented. On top of that the X540 firmware is written with the assumption that is does not need to be reset for proper initialization so it's not needed. I'm just assigning the pointer at NULL as the current implementation is rather misleading.

2011-03-03ixgbe: add polling test to end of PHY resetEmil Tantilov

2011-03-03ixgbe: Check link wants report current link stateEmil Tantilov
Currently check link reports the link state as down, if at any time the link had previously gone down since the last time the LINKS register was read. This does not accurately reflect the function of the check link call, which should be to return the CURRENT link state. Code now reads the LINKS registers twice, once to clear the previous and again to get the current value.

2011-03-03ixgbe: Add ability to double reset on failure to clear master enableEmil Tantilov
Double resets are required for recovery from certain error conditions. Between resets, it is necessary to stall to allow time for any pending HW events to complete. We use 1usec since that is what is needed for ixgbe_disable_pcie_master(). The second reset then clears out any effects of those events.

When support for 82577/82578 was added[1] in 2.6.31, PHY wakeup was in- advertently enabled (even though it does not function properly) on ICH10 LOMs. This patch makes it so that the ICH10 LOMs use MAC wakeup instead as was done with the initial support for those devices (i.e. 82567LM-3, 82567LF-3 and 82567V-4).

2011-02-28sfc: Remove configurable FIFO thresholds for pause frame generationBen Hutchings
In Falcon we can configure the fill levels of the RX data FIFO which trigger the generation of pause frames (if enabled), and we have module parameters for this. Siena does not allow the levels to be configured (or, if it does, this is done by the MC firmware and is not configurable by drivers). So far as I can tell, the module parameters are not used by our internal scripts and have not been documented (with the exception of the short parameter descriptions). Therefore, remove them and always initialise Falcon with the default values. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>
