Throughout the document, when it says:

8.1.26    must indicate that they are
   finished sending a particular record by including the SCTP_EOR flag.

but I can not find where to use SCTP_EOR flag.


5.1  The msg_flags are not used when sending a message with sendmsg().

3.1.4  flags:  No new flags are defined for SCTP at this level.  See
      Section 5 for SCTP-specific flags used in the msghdr structure.

4.1.8 same with 3.1.4

9.10, 9.12    flags:  The same flags as used by the sendmsg() call flags (e.g.,

9.7   flags:  The same as sinfo_flags (see Section 5.3.2).

5.3.2 sinfo_flags not mention about it  

It should say:

maybe msg_flags should be used.


Another problem is that, I think it should be discuss about debfine a flag like SCTP_BOR for beginning(init chunk) of a Record, because a stream of this socket(assoc) can still be used after send a SCTP_EOR.

And between a init chunk and a STCP_EOR, if I change SCTP_EXPLICIT_EOR status, what the socket will send the message?
6111 addresses the same problem and has a more actionable recommendation.
