 It looks like dynamic dection of optics type has been incorporated
 into the newest version if ixgbe.c, 1.17.2.12.2.2, with description
 
  217713  - Make phy detection dynamic so adapters that support multiple
  types of media can be properly identified by the interface layer
 
 Thus I believe kern/153951 should be closed.
