description:
Print NVM image version on 82598.

  FreeBSD ix-3.3.29 added code to decode NVM version. On 82598, the NVM
  offset is NVM_EEP_OFFSET_82598(== 0x2a). My own three different 82598
  cards' value in NVM_EEP_OFFSET_82598 are 0xffff. Instead, the dev starter
  version (0x29) has the value. Two of them have 0x1070 and another has 0x2090.
  The 82598 specification update notes about 2.9.0.
