This counts the number of times an FCIP Special Frame, used during FCIP link establishment and verification, was expected but not received on this link. Because Special Frame exchange is part of the FCIP link setup handshake, repeated failures to receive it can prevent the link from establishing cleanly or cause it to bounce right after coming up, making this counter a useful early diagnostic for a link that will not stabilize. A newly configured FCIP link that keeps flapping shortly after being brought up, paired with a climbing count here, points to the Special Frame handshake itself failing rather than a general connectivity problem.
