ifXTable.

This mixin supports the quasi static information from both tables
together in one hash, see below.

is the common ifIndex into the ifTable and ifXtable:

{
INTEGER => { # ifIndex as key

ifName => DisplayString, # ifXTable entries
ifAlias => DisplayString,
ifHighspeed => GAUGE,

ifDescr => DisplayString, # ifTable entries
ifType => IANAifType,
ifMtu => INTEGER,
ifSpeed => GAUGE,
ifPhysAddress => PhysAddress,
ifAdminStatus => INTEGER,
ifOperStatus => INTEGER,
}

...,
}
