bridge: trigger RTM_NEWLINK when interface is modified by bridge ioctl
Currently, there is a difference in netlink events received when an
interface is modified through bridge ioctl() or through netlink. This
patch generates additional events when an interface is added to or
removed from a bridge via ioctl().
When adding then removing an interface from a bridge with netlink, we
get:
