Modify fnic driver interfaces to use FDLS and supporting functions. Refactor code in fnic_probe and fnic_remove. Get fnic from shost_priv. Add error handling in stats processing functions. Modify some print statements. Add support to do module unload cleanup. Use placeholder functions/modify function declarations to not break compilation.
