0x23 protocol info?

I'm seeing packets like this (from an RTL8305NB):

09:15:14.290876 52:54:4c:83:09:e0 > ff:ff:ff:ff:ff:ff, ethertype RRCP (0x8899), length 60: 52:54:4c:83:09:e0 > ff:ff:ff:ff:ff:ff, RRCP-0x23 query
        0x0000:  ffff ffff ffff 5254 4c83 09e0 8899 2300  ......RTL.....#.

        0x0030:  0000 0000 0000 0000 0000 0000            ............

I see from #3 that there's no documentation on 0x23, at least there wasn't at the time. Have there been any new discoveries since?

Seems it is published. From the RTL8305NB-CG datasheet, it's a loop detection packet:
