    tipc: add link get/dump to new netlink api · 7be57fc6
    Richard Alpe 提交于
    Add TIPC_NL_LINK_GET command to the new tipc netlink API.
    
    This command supports dumping all information about all links
    (including the broadcast link) or getting all information about a
    specific link (not the broadcast link).
    
    The information about a link includes name, transmission info,
    properties and link statistics.
    
    As the tipc broadcast link is special we unfortunately have to treat
    it specially. It is a deliberate decision not to abstract the
    broadcast link on this (API) level.
    
    Netlink logical layout of link response message:
