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
code so that we now populate the values prior to allocating the q_vectors
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.

This patch adds an alternative tx status path
for BlockAck Requests as the hardware doesn't
recognize that a BlockAck Requests is usually
acked with a BlockAck and not a legacy ACK.

Without this patch, the stack would constantly
resent old and stale BARs. So, depending on the
receiver stack, this could lead to:

 - "stuck" ba sessions and package loss, as the
   stale BAR would reset the sequence each time.

 - lots of reorder releases.

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.

This patch replaces a switch statement for an 82598 workaround with an if
statement that only applies to 82598. In addition I am pulling out several
dead pieces of code and instead of reading the SRRCTL register and then
modifying it we are just writing a value which we generate from scratch.
Finally I am also removing any drop enable related code since that was
moved to a function of its own.

We are currently using indices to indicate the upper limit on a ring
feature.  However since we can switch back and forth on features such as
DCB and that has effects on other features such as RSS it is preferable to
instead store the upper limit separate from the current value for the
number of rings related to the feature.

actually needs the number of MSI-X vectors and that is in slow path.
