Re: M2PA: resynchronization of sequence numbers after PO

Hi Brian,

Perhaps this was not clear from the description in section 4.1.4 of RFC,
however section 
5.4 brings more doubts:
In figure 16, the "B"-side (the side that receives Link Status Processor
Recovered message),
after receiving LS PR and after sending LS Ready (stream 1) message "has
completed synchronization
of sequence numbers and has sent LS Ready, so it is able to resume sending
data at this point with
the new sequence numbers".

A side (the side that recovered from PO) sends the second LS Ready (stream
1) but it seems noone
does anything with that message: if the purpose of synchronization was to
send the last received BSN
to synchronize FSNs at remote peer, then two messages seem to be sufficient?

Best regards, Dario
