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.

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.

The mask value for ring features was overloaded for FCoE which can lead to
some confusion. In order to avoid any confusion I am splitting the mask
value and adding an offset value. This can be used for the start of the
FCoE rings, and in the future I hope to use it to store the start of the
registers for SR-IOV.

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.

It makes much more sense for us to count q_vectors instead of MSI-X
vectors. We were using num_msix_vectors to find the number of q_vectors in
multiple places. This was wasteful since we only had one place that
actually needs the number of MSI-X vectors and that is in slow path.
