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.
