Question #679313 on rohc changed:
https://answers.launchpad.net/rohc/+question/679313

yiyuechan gave more information on the question:
Hello,

    what I mean is that:

1.field =:= lsb(K,P) is a Library of Encoding Methods defined in RFC4997, the FN means it has decided a certain filed use the K bits LSB? e.g. seq_number =:= lsb(16, 32767). It means that k = 16 and p = 32767. it has decided the seq_number is encoded with 16bits LSB communicated to the decompressor? However, in the RFC3095, it tells we should calculate the value K according to the section 4.5.1 a),b),c),d) in RFC 3095.
SO,what is the field =:= lsb(K,P) ? where can I see the algorithm realization for it.
      when we use the LSB  encoding, we find or calculate the least K bits in the interval, but as for the field =:= lsb(K,P), the K is fixed，we only use it for the field , is it right?
2 in the lib 2.2.0, as for seq_number =:= lsb(16, 32767),I can not find the WLSB initialization with P = 32767?
