ifmedia changes:
- Extend the number of available subtypes for Ethernet media by using some of the ifmedia word's option bits to help denote subtypes. As a result, the number of possible Ethernet subtype values increases from 31 to 511. - Use some of those new values to define new media types. - lacp_compose_key() recgonizes the new Ethernet media types added. (Change made as required by a comment in if_media.h) - New ioctl, SIOGIFXMEDIA, to handle getting the new extended media types. SIOCGIFMEDIA is retained for backwards compatibility. - Changes to ifconfig to allow it to handle the new extended media types.
