Turns out we would reset the TSN seq counter during
a colliding INIT. This if fine except when we have
data outstanding... we basically reset it to the
previous value it was.. so then we end up assigning
the same TSN to two different data chunks.
This patch:
1) Finds a missing lock for when we change the stream
numbers during COOKIE and INIT-ACK processing.. we
were NOT locking the send_buffer.. which COULD cause
problems (found by inspection looking for <2>)
2) Fixes a case during a colliding INIT where we incorrectly
reset the sending Sequence thus in some cases duplicately
assigning a TSN.
3) Additional enhancments to logging so we can see strm/tsn in
the receiver AND new tracking to watch what the sender
is doing with TSN and STRM seq's.
