If we look closely, the 4 writes to TRANSMIT_CHL.id1 can be collapsed
down into much simpler code.  So do just that.

This also fixes a build failure due to the I/O macros no longer
getting pulled in.  Their minor (and accidental) usage here gets
dropped as part of the unification.

Results on dummy device can be seen in my netconf 2011
slides. These results are for a 10Gige IXGBE intel
nic - on another i5 machine, very similar specs to
the one used in the netconf2011 results.
It turns out - this is a hell lot worse than dummy
and so this patch is even more beneficial for 10G.

Test setup:
----------

System under test sending packets out.
Additional box connected directly dropping packets.
Installed prio qdisc on the eth device and default
netdev default length of 1000 used as is.
The 3 prio bands each were set to 100 (didnt factor in
the results).

5 packet runs were made and the middle 3 picked.

results
-------

The "cpu" column indicates the which cpu the sample
was taken on,
The "Pkt runx" carries the number of packets a cpu
dequeued when forced to be in the "dequeuer" role.
The "avg" for each run is the number of times each
cpu should be a "dequeuer" if the system was fair.

As you can see the system is still not perfect but
is a lot better than what it was before...

At the moment we use the old backlog weight, weight_p
which is 64 packets. It seems to be reasonably fine
with that value.
The system could be made more fair if we reduce the
weight_p (as per my presentation), but we are going
to affect the shared backlog weight. Unless deemed
necessary, I think the default value is fine. If not
we could add yet another knob.

    ixgbe: DCB, further cleanups to app configuration

Removed the getapp() routines from ixgbe because they are no
longer needed. It also allowed the set hardware routines to
use both IEEE 802.1Qaz app types and CEE app types. This
added code to do bit shifting in the IEEE case.

This patch reverts the checks and handles the IEEE case
from the setapp entry point. I prefer this because it
keeps the two paths from having to be aware of the DCB
mode. This resolves a bug where I missed setting the
selector bit in the IEEE spec value and left it in the
CEE value. Now that they are separate routines these types
of errors should not occur.

This patch updates the current methods used for determining if we have
enough space to transmit a given skb.  The current method is quite wasteful
as it has us go through and determine how each page is going to be broken
up.  That only needs to be done if pages are larger than our maximum data
per TXD.  As such I have wrapped that in a page size check.

There is a significant amount of shared functionality between the checksum
and TSO offload configuration that is shared in regards to how they setup
the context descriptors.  Since so much of the functionality is shared it
makes sense to move the shared functionality into a single function and
just call that function from the two context descriptor specific routines.

Restructures the logic used in tipc_port_recv_proto_msg() to ensure

applies on an existing connection and then processes the request.

be processed if it was sent to an unconnected port that had no names
bound to it.

duplicating the terminating port's standard payload message header
and adjusting the message size, importance, and error code fields,
rather than building all fields of the message from scratch. A FIN
message that is directed to the port itself is created the same way.
but also requires swapping the origin and destination address fields.

In addition to reducing the work required to create FIN messages,
these changes eliminate several instances of duplicated code,
