ixgbe/base: add flow control ethertype for filtering

This patch adds the flow control ethertype to the defines for the
ETQF filter list. This only adds the define. Each driver
can add this ethertype to the filter. This is needed to prevent
denial of service by malicious VFs sending out flow control
packets.
