What is fcmFLoginClass3DataFieldSize?

This is the Receive Data Field Size, in bytes, that the Fx_Port agreed to support for Class 3 frames with this Nx_Port, meaningful only when Class 3 service was agreed upon. Since Class 3 typically carries SCSI storage traffic, an admin checks this value to confirm the negotiated frame size aligns with expected storage throughput for that connection.
