In FC fabrics with large zones, the automatic port_rescan on incoming ELS and any adapter recovery can cause quite some traffic at the very same time, especially if lots of Linux images share an HBA, which is common on s390. This can cause trouble and failures. Fix this by making such port rescans dependent on a user configurable module parameter. The following unconditional automatic port rescans remain as is: On setting an adapter online and on manual user-triggered writes to the sysfs attribute port_rescan.
