[PATCH 3/3] drivers/net: add support for IF-MIB and EtherLike-MIB for ixgbe

[Michal Jastrzebski <michalx.k.jastrzebski@intel.com>]

If-MIB xstats:
ifNumber
ifIndex
ifType
ifMtu
ifSpeed
ifPhysAddress
ifOperStatus
ifLastChange
ifHighSpeed
ifConnectorPresent
ifCounterDiscontinuityTime

EtherLike-MIB xstats:
dot3PauseOperMode
dot3StatsDuplexStatus
dot3StatsRateControlAbility
dot3StatsRateControlStatus
dot3ControlFunctionsSupported
