ixgbe: Add RING_F_FCOE for FCoE feature in 82599

Add ring feature for FCoE to make use of the FCoE redirection
table in 82599. The FCoE redirection table is a receive side
scaling feature for Fiber Channel over Ethernet feature in 82599,
enabling distributing FCoE packets to different receive queues
based on the exchange id.
