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.
