ixgbe: convert low_water into an array
Since fc.high_water is an array, we should treat low_water as an array
also. This allows the algorithm to output different values for different
TCs, and then we can distinguish between them. In addition, this patch
changes one path that didn't honor the return value from ixgbe_setup_fc.

ixgbe: add Linux NICS mailing list to contact info
This patch updates the contact information on the ixgbe driver files so
that every file includes the Linux NICS address, as it is still used,
but only a few of the files mentioned it.

ixgbe: Clean up priority based flow control
This change cleans up the logic in the priority based flow control
configuration routines. Both the 82599 and 82598 based routines perform
similar functions however they are both arranged completely differently.
This patch goes over both of them to clean up the code.
In addition I am dropping the ixgbe_fc_pfc flow control mode and instead
just replacing it with checks for if priority flow control is enabled.
This allows us to maintain some of the link flow control information which
allows for an easier transition between link and priority flow control.

ixgbe: Update link flow control to correctly handle multiple packet buffer DCB
This change updates the link flow control configuration so that we
correctly set the link flow control settings for DCB. Previously we would
have to call the fc_enable call 8 times, once for each packet buffer. If
we move that logic into the fc_enable call itself we can avoid multiple
unnecessary register writes.
This change also corrects an issue in which we were only shifting the water
marks for 82599 parts by 6 instead of 10. This was resulting in us only
using 1/16 of the packet buffer when flow control was enabled.

ixgbe: X540 devices RX PFC frames pause traffic even if disabled
Receiving PFC (priority flow control) frames while the feature
is off should not pause the traffic class. On the X540 devices
the traffic class react to frames if it was previously enabled
because the field is incorrectly cleared.

ixgbe: update {P}FC thresholds to account for X540 and loopback
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.

ixgbe: PFC not cleared on X540 devices
X540 devices do not clear PFC before sets. This results in
the device possibly responding to PFC frames that the user
has disabled. Although it would also be wrong for the peer
to be transmitting these frames. Now we clear the register
before set.
