Subject: bnx2x: Prevent false warning for lack of FC NPIV
From: Yuval Mintz <Yuval.Mintz@xxxxxxxxxx>
commit 1e6bb1a3540fec3ef112b9a89dda88e684c3ff59 upstream.
Not all adapters have FC-NPIV configured. If bnx2fc is used with such an
adapter, driver would read irrelevant data from the the nvram and log
"FC-NPIV table with bad length..." In system logs.
Simply accept that reading '0' as the feature offset in nvram indicates
the feature isn't there and return.
