New question #232430 on rohc:
https://answers.launchpad.net/rohc/+question/232430

In rohc-1.6.0 code packet, Function code_IR_packet(Line 1803), there is a process : 
g_context->code_ir_remainder(context, dest, counter)

this used to add a remainder header to the ROHC packet.

But according to RFC3095(Page 97),  IR packet (5.7.7.1),  there is not anything described 
about the "remainder header"

5.7.7.1.  Basic structure of the IR packet
  --- --- --- --- --- --- --- ---
   |         Add-CID octet         |  if for small CIDs and CID != 0
   +---+---+---+---+---+---+---+---+
   | 1   1   1   1   1   1   0 | D |
   +---+---+---+---+---+---+---+---+
   |                               |
   /    0-2 octets of CID info     /  1-2 octets if for large CIDs
   |                               |
   +---+---+---+---+---+---+---+---+
   |            Profile            |  1 octet
   +---+---+---+---+---+---+---+---+
   |              CRC              |  1 octet
   +---+---+---+---+---+---+---+---+
   |                               |
   |         Static chain          |  variable length
   |                               |
   +---+---+---+---+---+---+---+---+
   |                               |
   |         Dynamic chain         |  present if D = 1, variable length
   |                               |
    - - - - - - - - - - - - - - - -
   |                               |
   |           Payload             |  variable length
   |                               |
    - - - - - - - - - - - - - - - -

It seems that the code is not associate with the RFC. 


Where can i find the discription about the "remainder header" of IR/IR-DYN packet?

Thanks a lot.
