This parameter adds support for SR-IOV.  It causes the driver to spawn up to

max_vfs worth of virtual function.



QueuePairs

----------

Valid Range:  0-1

Default Value:  1 (TX and RX will be paired onto one interrupt vector)



If set to 0, when MSI-X is enabled, the TX and RX will attempt to occupy

separate vectors.



This option can be overridden to 1 if there are not sufficient interrupts

available.  This can occur if any combination of RSS, VMDQ, and max_vfs

results in more than 4 queues being used.



Node

----

Valid Range:   0-n

Default Value: -1 (off)



  0 - n: where n is the number of the NUMA node that should be used to

         allocate memory for this adapter port.

  -1: uses the driver default of allocating memory on whichever processor is

      running insmod/modprobe.



  The Node parameter will allow you to pick which NUMA node you want to have

  the adapter allocate memory from.  All driver structures, in-memory queues,

  and receive buffers will be allocated on the node specified.  This parameter

  is only useful when interrupt affinity is specified, otherwise some portion

  of the time the interrupt could run on a different core than the memory is

  allocated on, causing slower memory access and impacting throughput, CPU, or

  both.



EEE

---

Valid Range:  0-1

Default Value: 1 (enabled)



  A link between two EEE-compliant devices will result in periodic bursts of

  data followed by long periods where in the link is in an idle state. This Low

  Power Idle (LPI) state is supported in both 1Gbps and 100Mbps link speeds.

  NOTE: EEE support requires autonegotiation.



DMAC

----

Default Value: 1 (enabled)

  Enables or disables DMA Coalescing feature.
