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.

Hi Dave,
Please consider applying this to `net'.
Thanks,
