The driver currently skips setting this flag if the VPD contains the
firmware version string. We fix this by separating the probing of NCSI
from the reading of the NCSI version string. The APE_HAS_NCSI flag is
needed to properly read sensor data.

skb_fill_rx_data() pulls 64 byte of data in skb->data
Its too much for TCP (with no options) on IPv4, as total size of headers
is 14 + 40 = 54
This means tcp stack and splice() are suboptimal, since tcp payload
is in part in tcp->data, and in part in skb frag.

In upcoming patches it will become increasingly common to need to determine
the FCoE traffic class in order to determine the correct queues for FCoE.
In order to make this easier I am adding a function for obtaining the FCoE
traffic class based on the user priority.

There were cases where the prio_tc_map was not populated when we were
calling open. This will result in us incorrectly configuring the traffic
classes when DCB is enabled. In order to correct this I have updated the

and calling ixgbe_open.

This is meant to be a generic clean-up of the remaining functions for
unpacking data from the DCB structures. The only real changes are:
replaced the variable i with tc for functions that were looping through the
traffic classes, and added a pointer for tc_class instead of path since
that way we only need to pull the pointer once instead of once per loop.

This patch is meant to help simplify the logic for getting traffic classes
from user priorities. To do this I am adding a function named
ixgbe_dcb_get_tc_from_up that will go through the traffic classes in
reverse order in order to determine which traffic class contains a bit for
a given user priority.
Adding a declaration for this new function to the header so that
we have a centralized means for sorting out traffic classes belonging to
features such as FCoE.

A number of older ColdFire CPU based boards use NS8390 based network
controllers. Most use the Davicom 9008F or the UMC 9008F. This driver
provides the support code to get these devices working on these platforms.
Generally the NS8390 based eth device is direct connected via the general
purpose bus of the ColdFire CPU. So its addressing and interrupt setup is
fixed on each of the different platforms (classic platform setup).
This driver is based on the other drivers/net/ethernet/8390 drivers, and
includes the lib8390.c code. It uses the existing definitions of the
board NS8390 device addresses, interrupts and access types from the
arch/m68k/include/asm/mcf8390.h, but moves the IO access functions into
the driver code and out of that header.

There are really only 3 modes that can control the number of queues. Those
are RSS, DCB, and VMDq/SR-IOV. Currently we have things much more broken
up than they need to be for how we are configuring the rings. In order to
try and straiten some of this out I am going to start merging similar
functionality into single functions. To start with I am merging the Flow
Director ring configuration into the RSS ring configuration since Flow
Director cannot function with DCB or SR-IOV.

We are currently using indices to indicate the upper limit on a ring

instead store the upper limit separate from the current value for the
