    qemu: support live update of an interface's filter · 258fb278
    Laine Stump 提交于
    Since we can't (currently) rely on the ability to provide blanket
    support for all possible network changes by calling the toplevel
    netdev hostside disconnect/connect functions (due to qemu only
    supporting a lockstep between initialization of host side and guest
    side of devices), in order to support live change of an interface's
    nwfilter we need to make a special purpose function to only call the
    nwfilter teardown and setup functions if the filter for an interface
    (or its parameters) changes. The pattern is nearly identical to that
    used to change the bridge that an interface is connected to.
    
    This patch was inspired by a request from Guido Winkelmann
    <guido@sagersystems.de>, who tested an earlier version.
