[cgutman] 43287: - Don't add the media-specific header until right before transmission - Previously we would store the largest media-specific header size and add that value when creating a packet - Makes loopback packets smaller because they have no need for a media-specific header - Would fix packet corruption if interfaces with different media-specific headers were installed (if we supported that) - Makes adding support for other media types easier

Log:
- Don't add the media-specific header until right before transmission
- Previously we would store the largest media-specific header size and add that value
when creating a packet
- Makes loopback packets smaller because they have no need for a media-specific header
- Would fix packet corruption if interfaces with different media-specific headers were
installed (if we supported that)
- Makes adding support for other media types easier
