Log Message:
Add some new event counters.

Add the following counters for 82575 and newer except 80003, ICHs and PCHs:
    - Only 82576 document describes about the circuit breaker,
      so the following two might be only for 82575:
        - Circuit Breaker TX Manageability Packet
        - Circuit Breaker RX Dropped Packet
    - 82575's document doesn't describe the following two, but we can see
      the same value as GO{T,R}C have:
        - Host Good Octets RX
        - Host Good Octets TX
    - 82575's document doesn't describe the LENERRS (Length Errors) counter.
      I don't know if it has.
    - Perhaps Non-SerDes/SGMII devices don't have SCVPC
      (SerDes/SGMII Code Violation Packet) register. We don't care if
      it's SerDes/SGMII or not for now.
    - HRMPC (Header Redirection Missed Packet) appears only once
      in 8257[56]'s datasheet. FreeBSD's igb counts it, so we do, too.
    - Count the following two for I350 and newer. I don't know if PCHs have:
        - EEE TX LPI
        - EEE RX LPI
