Add code to enable thermal sensors for the x540 hardware, as well as a
thermal interrupt check which will exit with a critical message of a
thermal overheat is detected. Intent of code allows other mac types to
be added with different configuration in the future.
Fixed in this version is the addition of setting the temp_sensor
capable flag which was previously only set for a specific mac.

Revise high and low threshold marks wrt flow control to account
for the X540 devices and latency introduced by the loopback
switch.
Without this it was in theory possible to drop frames on a
supposedly lossless link with X540 or SR-IOV enabled.
Previously we used a magic number in a define to calculate the
threshold values. This made it difficult to sort out exactly
which latencies were or were not being accounted for. Here
I was overly explicit and tried to used #define names that would
be recognizable after reading the IEEE 802.1Qbb specification.

This patch is meant to help cleanup the interrupt throttle rate logic by
storing the interrupt throttle rate as a value in microseconds instead of
interrupts per second. The advantage to this approach is that the value
can now be stored in an 16 bit field and doesn't require as much math to
flip the value back and forth since the hardware already used microseconds
when setting the rate.

Use the PCI device flag indicating if a VF is assigned to a guest VM
to guard against destroying VFs upon driver removal. Implement
additional feature to detect if VFs already exist when the driver
is loaded and if so configure them and set the driver state to
SR-IOV enabled.

This patch improves the memory utilization with RSC when in one-buffer
mode. This is accomplished by making the default buffer sizes match up
with the standard memory allocation sizes minus 1K for shared info and
padding overhead. By doing this CPU utilization when doing large receives
can be reduced by as much as 8%.

It was possible to inadvertently add additional interrupt causes to the
MSI-X other interrupt. This occurred when things such as RX buffer overrun
events were being triggered at the same time as an event such as a Flow
Director table reinit request. In order to avoid this we should be
explicitly programming only the interrupts that we want enabled. In
addition I am renaming the ixgbe_msix_lsc function and interrupt to drop
any implied meaning of this being a link status only interrupt.
Unfortunately the patch is a bit ugly due to the fact that ixgbe_irq_enable
needed to be moved up before ixgbe_msix_other in order to have things
defined in the correct order.

This change consolidates all of the MSI-X interrupt and polling routines
into two single functions. One for the interrupt and one for the code.
The main advantage to doing this is that the compiler can optimize the
routines into single monolithic functions which should allow all of them
function to occupy a single block of memory and as such avoid jumping
around.

This change makes it so that the default Tx work limit is 256 buffers or
1/2 of an entire ring instead of a full ring size so that it is much more
likely that we will be able to actually reach the work limit value.
Previously with the value set to an entire ring it would not have been
possible for us to trigger an event due to the fact that the Tx work is
stopped at the point where we cannot place one more buffer on the ring and
it is not restarted until cleanup is complete.
