    bridge: Allow mcast snooping for transient link local addresses too · e4de9f9e
    Linus Lüssing 提交于
    Currently the multicast bridge snooping support is not active for
    link local multicast. I assume this has been done to leave
    important multicast data untouched, like IPv6 Neighborhood Discovery.
    
    In larger, bridged, local networks it could however be desirable to
    optimize for instance local multicast audio/video streaming too.
    
    With the transient flag in IPv6 multicast addresses we have an easy
    way to optimize such multimedia traffic without tempering with the
    high priority multicast data from well-known addresses.
    
    This patch alters the multicast bridge snooping for IPv6, to take
    effect for transient multicast addresses instead of non-link-local
    addresses.
