Subject: netxen_nic: Log proper error message in case of mismatched adapter type
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=b08a92bb7381ff03d4101bcc61e65120bc690a4f;p=linux-beck.git

netxen_nic: Log proper error message in case of mismatched adapter type

o log "Unknown" board name and "Unknown" serial number in case
  of mismatched adapter type found. This will avoid weird characters
  logs when an adapter is in bad state or corrupted.
