Notes:
1. The actual value is between 0 and the LOGIN_BB_Credit.
2. LPEfx is useful for resetting bypass circuits of NL_Ports which have lost their address.
3. Any NL_Port receiving an MRK attempts to forward it, StorageTek does not originate it.
4. This feature may be disabled by a configuration item change.
5. Our target will accept the Open Full Duplex but the FCP simplex protocol does not take
advantage of the full duplex capabilities.
