Detailed Description

Option field for an DsrFsHeader Enables adding options to an DsrFsHeader.

Implementor's note: Make sure to add the result of OptionField::GetSerializedSize () to your DsrFsHeader::GetSerializedSize () return value. Call OptionField::Serialize and OptionField::Deserialize at the end of your corresponding DsrFsHeader methods.
