[PATCH v2] drivers/net: add support for IF-MIB and EtherLike-MIB for ixgbe

[Radu Nicolau <radu.nicolau@intel.com>]

From: 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

-updated in v2: coding style
