During the login process, the peer ports exchange a nonzero BB_SC_N value.
During frame transmission/reception, one port maintains counters to track the
R_RDY and frames received. Based on a periodic exchange of BB_SC_N values,
the receiving port determines how many R_RDYs should have been received.
BB-CR compares this value with the actual counters maintained at the receiving
port, from which the receiver can compute the actual quantity of credits lost, and
thus recover without incurring a link reset.
By default, BB-CR functionality is enabled on Marvell QLogic 2600 and 2770
Series Adapters that are operating at 16Gbps or higher, and that integrate with
Brocade Fabric OS Manager and Brocade Network Advisor.
From the FC Adapter Configuration menu, select the BB Credit Recovery option.
The following menu options allow you to view, enable, or disable support for
BB-CR on the selected adapter port:
BB Credit Config Menu
1: Info (shows the BB Credit Status as Enabled or Disabled)
2: Enable (enables BB-CR; requires a reboot to take effect)
3: Disable (disables BB-CR; requires a reboot to take effect)
