The Intel I211 Ethernet Controller supports 2 Receive Side Scaling (RSS) queues. It should not be excluded from having this feature enabled. Via commit c883de9fd787b6f49bf825f3de3601aeb78a7114 E1000_MRQC_ENABLE_RSS_4Q was renamed to E1000_MRQC_ENABLE_RSS_MQ to indicate that this is a generic bit flag to enable queues and not a flag that is specific to devices that support 4 queues The bit flag enables 2, 4 or 8 queues appropriately depending on the part. Tested with a multicore CPU and frames were then distributed as expected. This issue appears to have been introduced because of confusion caused by the prior name.
