     96    The only change is:
     97    IFF_LOOPBACK, IFF_BROADCAST and IFF_POINTOPOINT are
     98    more not changeable by user. They describe link media
     99    characteristics and set by device driver.
    100 
    101    Comments:
    102    - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid
    103    - If neither of these three flags are set;
    104      the interface is NBMA.
    105 
    106    - IFF_MULTICAST does not mean anything special:
    107    multicasts can be used on all not-NBMA links.
    108    IFF_MULTICAST means that this media uses special encapsulation
    109    for multicast frames. Apparently, all IFF_POINTOPOINT and
    110    IFF_BROADCAST devices are able to use multicasts too.
