Feature #6285: Native Fiber Channel Support
Fibre Channel port down is not reliable/safe
Active testing of bringing FC ports up/down under load exposed numerous issues in that area, causing full range of problems from stuck commands to system crashes. It was not critical for existing FreeNAS FC users since ports there were brought up only once and never brought down. But it becomes more important for FC ports controlled by ctld, that will be brought down in case of ctld service stop. I've already localized two bugs, but I suppose there more.
