@TheBlueMatt The selection of which frames to use for MPTUD probes could be left to the implementations. I doubt that implementations that go into trouble of implementing PLPMTUD would be naive enough to not think carefully of this issue.

In fact, I think data frames could be better for MPTUD probes than useless PING/PADDING in some cases.  Imagine having two streams at different priorities ready to transmit.  You can send high-priority stream's data using known-good packet sizes, while fill your PMTUD probes with low-priority stream's data.
