New Revision: 184047
URL: http://svn.freebsd.org/changeset/base/184047

Log:
  MFC r183814:
    Read PCI device id instead of PCI revision id. Also checks the read
    device id is JMC260 family. Previously it just verified the deivce
    is JMC260 Rev A0. This will make it easy for newer JMC2xx support.

  MFC r183859:
    Make sure to read the last byte of EEPROM descriptor. Previously
    the last byte of the ethernet address was not read which in turn
    resulted in getting 5 out of the 6 bytes of ethernet address and
    always returned ENOENT. I did not notice the bug on FPGA version
    because of additional configuration data in EEPROM.
