Specifies the Ipv4 multicast address to be used as the destination
for performing an OAM ping operation when tmnxOamPingCtlTestMode has a
value of 'mfibPing' in which case this parameter is required. If
tmnxOamPingCtlTestMode is different from 'mfibPing' this field is
ignored.
This object was obsoleted in release 4.0 and replaced with
InetAddress objects tmnxOamMfibPingCtlDestAddrType and
tmnxOamMfibPingCtlDestAddress.
