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. Reported-by: Andrew Patterson Signed-off-by: Yuval Mintz Signed-off-by: David S.
