As the new shepherding AD for 6LO, I just found a reported (i.e., neither 
verified nor closed) erratum on RFC 4944, "Transmission of IPv6 Packets over 
IEEE 802.15.4 Networks". https://www.rfc-editor.org/errata_search.php?eid=6194 
This erratum was never posted to the 6LO list probably due to a technical issue.

What is the WG view on this erratum ?

Thank you in advance for the discussion.

Regards

The reported errata is:

Reported By: Tommaso Pecorella
Date Reported: 2020-05-30
Section 6 says:
However, in the
   resultant interface identifier, the "Universal/Local" (U/L) bit SHALL
   be set to zero in keeping with the fact that this is not a globally
   unique value.

It should say:
However, in the
   resultant interface identifier, the "Universal/Local" (U/L) bit SHALL
   be set to one in keeping with the fact that this is not a globally
   unique value.

Notes:
IEEE (see 
https://standards.ieee.org/content/dam/ieee-standards/standards/web/documents/tutorials/eui.pdf)
 states that:
"the second least significant bit of Octet 0 (the U/L bit) indicates universal 
(U/L=0) or local (U/L=1) administration of the address."
Thus, the U/L bit in the "pseudo 48-bit address" shall have its U/L bit set to 
one, not to zero.
