    bridge: netlink: make setlink/dellink notifications more accurate · e19b42a1
    Nikolay Aleksandrov authored
    Before this patch we had cases that either sent notifications when there
    were in fact no changes (e.g. non-existent vlan delete) or didn't send
    notifications when there were changes (e.g. vlan add range with an error in
    the middle, port flags change + vlan update error). This patch sends down
    a boolean to the functions setlink/dellink use and if there is even a
    single configuration change (port flag, vlan add/del, port state) then
    we always send a notification. This is all done to keep backwards
    compatibility with the opportunistic vlan delete, where one could
    specify a vlan range that has missing vlans inside and still everything
    in that range will be cleared, this is mostly used to clear the whole
    vlan config with a single call, i.e. range 1-4094.
