igb: Enable RSS for Intel I211 Ethernet Controller
The Intel I211 Ethernet Controller supports 2 Receive Side Scaling (RSS)
queues. It should not be excluded from having this feature enabled.
Via commit c883de9fd787 ("igb: rename igb define to be more generic")
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.
