They describe link media 633 characteristics and set by device driver. 634 635 Comments: 636 - Combination IFF_BROADCAST|IFF_POINTOPOINT is invalid 637 - If neither of these three flags are set; 638 the interface is NBMA. 639 640 - IFF_MULTICAST does not mean anything special: 641 multicasts can be used on all not-NBMA links. 642 IFF_MULTICAST means that this media uses special encapsulation 643 for multicast frames. Apparently, all IFF_POINTOPOINT and 644 IFF_BROADCAST devices are able to use multicasts too. 645 */ 646 647/* IFLA_LINK. 648 For usual devices it is equal ifi_index. 649 If it is a "virtual interface" (f.e. tunnel), ifi_link 650 can point to real physical interface (f.e. for bandwidth calculations), 651 or maybe 0, what means, that real media is unknown (usual 652 for IPIP tunnels, when route to endpoint is allowed to change) 653 */ 654 655/* Subtype attributes for IFLA_PROTINFO */ 656enum 657{ 658 IFLA_INET6_UNSPEC, 659 IFLA_INET6_FLAGS, /* link flags */ 660 IFLA_INET6_CONF, /* sysctl parameters */ 661 IFLA_INET6_STATS, /* statistics */ 662 IFLA_INET6_MCAST, /* MC things.
