ixgbe: Allow Priority Flow Control settings to survive a device reset
When changing DCB parameters, ixgbe needs to have the MAC reset. The way
the flow control code is setup today, PFC will be disabled on a reset.
This patch adds a new flow control type for PFC, and then has the netlink
layer take care of toggling which type of flow control to enable.
