A second Ethertype value to be compared in order to match
this classifier entry. This value is considered in addition
to the value specified by agentDiffServAuxMfClfrEtypeVal1 and serves
as a second possible match value (i.e. a packet can match either
EtypeVal1 or EtypeVal2). The allowed value for this object is
0x0600 to 0xFFFF, with a value of 0 used to indicate this object is
not involved in the classifier entry.
