Description of problem:
Needs to add a support to Handle FPIN-li events for NVMe in multipathd.
At present we have the support for only scsi devices(EP).
When link integrity issues are detected on a Fibre Channel fabric,
A Link Integrity Fabric Performance Impact Notification (FPIN-Li) can be send to a node.
If multipathd listens for these events, it can use them to control a path's marginal status,
instead of trying to detect marginal paths internally.
The path will remain marginal until a registered state change notification (RSCN) or Link Up event is received.
Version-Release number of selected component (if applicable):
RHEL9.4
Actual results:
Multipathd has a more robust method of detecting marginal paths on Fibre Channel fabrics that can issue PFIN-Li events.
Additional info:
This feature which support scsi is already part of RHEL9.0 and RHEL8.7
