Subject: [net-next] igb: remove references to long gone command line parameters

From: Fernando Luis Vazquez Cao <fernando_b1@....ntt.co.jp>

Command line parameters QueuePairs, Node, EEE, DMAC and InterruptThrottleRate
do not exist these days. Remove all references to them in the Documentation
folder and update code comments.

@@ -36,54 +36,6 @@ Default Value: 0
 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
-----
-Valid Range: 0-1
-Default Value: 1 (enabled)
-  Enables or disables DMA Coalescing feature.
