[3/5] scsi: bnx2fc: clean up header definitions

Commit Message

Sebastian Andrzej Siewior Nov. 18, 2016, 10:10 a.m. UTC

- All symbols which are only used within one .c file are marked static
  and removed from the bnx2fc.h file if possible.

- the declarion of bnx2fc_percpu is moved into the header file

This patch was only compile-tested due to -ENODEV.
