DPD sequence number is not handled properly. Imagine a situation when we
lost connectivity for few seconds.
In this time we send, eg. 3 DPD packets (we also increase sequance
number). When the connectivity comes back we receive 3 ACKs, but only
the last one is accepted and the others are logged as errors.
The patch fixes the problem by maintaining correct sequence numbers
