New Revision: 223249
URL: http://svn.freebsd.org/changeset/base/223249

Log:
  MFC r220727-220728:
  - Read RX/TX chainmasks directly of the EEPROM. Some chips are known to
    have the wrong/broken information stored, keep the hardcoded values for
    those.
  - Bring over the HAL/OPS changes, instead of two const structs it is now
    slightly more dynamic.
