Hi Ben,

Actually doing manual uploads is always a problem.

Here is the text change I proposed as an editor's note that Deborah could put in the IESG writeup if that satisfactorily resolves the issue. It will get picked up when I fix all the comments and issue a new version of the fully text.

OLD

9.  Carrying RFC6374 Packets over an LSP using an SFL

   The packet format of an RFC6374 Query message using SFLs is shown in
   Figure 5.

NEW

9.  Carrying RFC6374 Packets over an LSP using an SFL

   We illustrate the packet format of an RFC6374 Query message using
   SFLs for the case of an MPLS direct loss measurement in Figure 5.

END

=======

OLD

   RFC6378 and the optional UDP Return Object is defined in [RFC7876].

9.1.  RFC6374 SFL TLV

NEW

   RFC6378 and the optional UDP Return Object is defined in [RFC7876].

   Where a measurement other than an MPLS direct loss measurement is to
   be made, the appropriate RFC6374 measurement message is used (for
   example, one of the new types defined in this document) and this is
   indicated to the receiver by the use of the corresponding ACH type.

9.1.  RFC6374 SFL TLV

=========

Best regards

Stewart
