This enables or disables payload compression on this specific route. Like header compression, this requires the Datagram/Payload Compression feature to actually be licensed on the unit per cdmipPayloadCompressionOption, and the set explicitly fails with 'commit_failed' rather than silently succeeding if that license is not present. Enabling this on a route carrying bandwidth-heavy but compressible plain-text traffic, on a unit that does have the payload compression license, would reduce the effective satellite airtime consumed by that route's traffic.
