* rt_netlink.c: (netlink_link_change) If the status of an
operative interface changes (e.g. MTU changes), the client
daemons should be notified by calling zebra_interface_up_update.
Previously, the information was being updated in zebra's
interface structure, but the clients were not notified of
changes to an operative interface.
* ospf_zebra.c: (ospf_interface_state_up) If the MTU of an operative
interface changes, print a debug message and call ospf_if_reset()
to simulate down/up on the interface.
* ospf_interface.h: Declare new function ospf_if_reset().
* ospf_interface.c: (ospf_if_reset) New function to call ospf_if_down
and ospf_if_up for all ospf interfaces attached to an interface.
