What is fcmPortBBCreditZeros?

This Counter64 counts how many times this port's outbound buffer-to-buffer credit has transitioned to and from zero, meaning the far end briefly stopped providing any credit to send frames. A rising count signals buffer starvation on the link, which an admin would investigate as a sign of a congested or slow-draining device on the other end.
