Hundreds.
We now introduce a simple backoff algorithm for these cases. The first five messages are sent at default rate; thereafter a message is sent only each 16't timer interval.

This will cover the vast majority of link recyling cases, since the

endpoint starting last will transmit at the higher speed, and the link should normally be established well be before the rate needs to be reduced. The only case where we will see a degradation of link re-establishment is when the endpoins remain intact, and a glitch in the transmission

media is causing the link reset. We will then experience a worst-case re-establishing time of 6 seconds, something we deem acceptable. Acked-by: Ying Xue <ying....@windriver.com> Signed-off-by: Jon Maloy <jon.ma...@ericsson.com>
