Report standard pause frame stats. They are already aggregated
in struct ixgbe_hw_stats.
The combination of the registers is suggested as equivalent to
PAUSEMACCtrlFramesTransmitted / PAUSEMACCtrlFramesReceived
by the Intel 82576EB datasheet, I could not find any information
in the HW actually supported by ixgbe.
