* (general) SPF millisecond resolution timer with adaptive,
linear back-off holdtime. Prettification of ospf_timer_dump.
* ospf_dump.c: (ospf_timeval_dump) new function. The guts of
ospf_timer_dump, but made to be more dynamic in printing out
the relative timeval, sliding the precision printed out
according to the value.
(ospf_timer_dump) guts moved to ospf_timeval_dump.
* ospf_dump.h: export ospf_timeval_dump.
* ospf_flood.c: (ospf_flood) remove gettimeofday, use
the libzebra exported recent_time instead, as it's not
terribly critical to have time exactly right - the dropped
LSA will be retransmited to us if we don't ACK it.
* ospf_packet.c: (ospf_ls_upd_timer) Ditto, but here we're
not transmitting, just putting LSA back on update transmit list.
* ospfd.h: delay and holdtimes should be unsigned.
Add spf_max_holdtime and spf_hold_multiplier.
Update default defines for delay and hold time to be in msec.
(struct ospf) change the SPF timestamp to a struct timeval.
Remove ospf_timers_spf_(un)?set.
* ospfd.c: (ospf_timers_spf_{set,unset}) removed.
(ospf_new) initialise spf_max_holdtime and spf_hold_multiplier
* ospf_spf.c: (ospf_spf_calculate) SPF timestamp is a timeval
now, update with gettimeofday.
(ospf_spf_calculate_schedule) Change SPF timers to millisecond
resolution.
Make the holdtime be adaptive, with a linear increase in
holdtime ever consecutive SPF run which occurs within holdtime
of previous SPF, bounded by spf_max_holdtime.
* ospf_vty.c: Update spf timers commands.
(ospf_timers_spf_set) trivial helper.
(ospf_timers_throttle_spf_cmd) new command to set SPF delay,
initial hold and max hold times with millisecond resolution.
(ospf_timers_spf_cmd) Deprecated. Accept the old values,
convert to msec, truncate to new limits.
(no_ospf_timers_throttle_spf_cmd) set timers to defaults.
(no_ospf_timers_spf_cmd) deprecated form, same as previous.
(show_ip_ospf_cmd) Display SPF parameters and times.
(show_ip_ospf_neighbour_header) Centralise the 'sh ip os ne'
header.
(show_ip_ospf_neighbor_sub) Fix the field widths. Get rid of
the multiple spaces which were making the lines even longer.
(show_ip_ospf_neighbor_cmd) Use show_ip_ospf_neighbour_header
(show_ip_ospf_neighbor_all_cmd) ditto and fix the field
widths for NBMA neighbours.
(show_ip_ospf_neighbor_int) Use header function.
(show_ip_ospf_nbr_nbma_detail_sub) use sizeof for timebuf,
local array - safer.
(show_ip_ospf_neighbor_detail_sub) ditto
(ospf_vty_init) install the new SPF throttle timer commands.
