The value of tmnxDot1agCfmMaMepListMacAddress specifies the target
unicast MAC address used for transmitting CFM packets to the remote
MEPs for the specified MEPID.
Setting a unicast MAC address restricts the number of MEPIDs that can
be configured for an individual MA to a maximum of one (1). Setting the
address back to the default value will remove this restriction and will
result in the regular CCM multicast address being used. This value
cannot be set to any multicast or broadcast address.
