The value of tSapIngressMacCritInnerTagValue specifies the value to
match against the VID of the second VLAN tag in the packet
that is carried transparently through the service (the second vlan tag
after the service delimiting tags).
This object can only be set if tSapIngressMacCritType is set to 'vid(3)'.
The (default) value of '-1' indicates no VLAN tag matching will be
performed.
