* (general) OSPF fast, sub-second hello and 1s dead-interval
support. A warning fix. Millisec support for ospf_timer_dump.
Change auto-cost ref-bandwidth to add a comment to write out
of config, rather than printing annoying messages to vty on
startup.
* ospf_dump.c: (ospf_timer_dump) Print out milliseconds too.
Callers typically specify a length of 9, so most see
millisecs unless they specify the additional length.
* ospf_interface.h: (struct ospf_interface) new interface param,
fast_hello.
* ospf_interface.c: (ospf_if_table_lookup) add brackets,
gcc warning fix.
(ospf_new_if_params) Initialise fast_hello param.
(ospf_free_if_params) Check whether fast_hello is configured.
(ospf_if_new_hook) set fast_hello to default.
* ospf_ism.h: Wrap OSPF_ISM_TIMER_ON inside do {} while (0) to
prevent funny side-effects from its if statement when this
macro is used conditionally by other macros.
(OSPF_ISM_TIMER_MSEC_ON) new macro, set in milliseconds.
(OSPF_HELLO_TIMER_ON) new macro to set hello timer according
to whether fast_hello is set.
* ospf_ism.c: Update all setting of the hello timer to use
either OSPF_ISM_TIMER_MSEC_ON or OSPF_HELLO_TIMER_ON. The
former is used when hello is to be sent immediately.
* ospf_nsm.c: ditto
* ospf_packet.c: (ospf_hello) hello-interval is not checked
for mismatch if fast_hello is set.
(ospf_read) Annoying nit, fix "no ospf_interface" to be debug
rather than a warning, as it can be perfectly normal to
receive packets when logical subnets are used.
(ospf_make_hello) Set hello-interval to 0 if fast-hellos are
configured.
* ospf_vty.c: (ospf_auto_cost_reference_bandwidth) annoying
nit, don't vty_out if this command is given, it gets tired
quick.
(show_ip_ospf_interface_sub) Print the hello-interval
according to whether fast-hello is set or not.
Print the extra 5 millisec characters from (ospf_timer_dump)
if fast-hello is configured.
(ospf_vty_dead_interval_set) new function, common to all
forms of dead-interval command, to set dead-interval and
fast-hello correctly. If a dead-interval is given, unset
fast-hello, else if a hello-multiplier is set, set
dead-interval to 1 and fast-hello to given multiplier.
(ip_ospf_dead_interval_addr_cmd) use
ospf_vty_dead_interval_set().
(ip_ospf_dead_interval_minimal_addr_cmd) ditto.
(no_ip_ospf_dead_interval) Unset fast-hello.
(no_ip_ospf_hello_interval) Bug-fix, unset of hello-interval
should set it to OSPF_HELLO_INTERVAL_DEFAULT, not
OSPF_ROUTER_DEAD_INTERVAL_DEFAULT.
(config_write_interface) Write out fast-hello.
(ospf_config_write) Write a comment about
"auto-cost reference-bandwidth" having to be equal on all
routers. Hopefully just as noticeable as old practice of
writing to vty, but less annoying.
(ospf_vty_if_init) install the two new dead-interval
commands.
* ospfd.h: Add defines for OSPF_ROUTER_DEAD_INTERVAL_MINIMAL
and OSPF_FAST_HELLO_DEFAULT.
