- Added support for multicast filtering, now that the firmware supports it. Note that this is not yet tested, as multicast seems to panic -current (even w/o mxge loaded) - Added workaround to cope with different irq data struct size on pre-multicast firmware which can found running on nics. - Added Intel E5000 PCIe chipsets to list providing aligned completions. - Replaced various magic constants with #defines, now that they are defined in the firmware headers.
