This object specifies the Delay Measurement frame size between
64 bytes and the maximum transmission unit of the EVC.
The range of frame sizes from 64 through 2000 octets need to be
supported, and the range of frame sizes from 2001 through 9600 octets
is suggested to be supported.
The adjustment to the frame size of the standard frame size is
accomplished by the addition of a Data or Test TLV. A Data or Test TLV
is only added to the frame if the frame size is greater than 64 bytes.
This object is only valid for the entity transmitting the Delay
Measurement frames (dmDmm, dm1DmTx) and is ignored by the entity
receiving frames.
In addition, this object is not valid when jnxSoamDmCfgVersion is 0.
This object can only be written at row creation time and cannot be
modified once it has been created.
