Get rid of ac->ac_ipaddr and arpwhohas() since they assume that
an interface has only one address.
Obtained from: BSD/OS 2.1, via Rich Stevens <rstevens@noao.edu>
Add five sysctl variables that you should probably never tweak.
net.arp.t_prune: 300
net.arp.t_keep: 1200
net.arp.t_down: 20
net.arp.maxtries: 5
net.arp.useloopback: 1
net.arp.proxyall: 0
(It's net.arp because arp isn't limited to inet, though our present
implementation surely is).
Removed ifnet.if_init and ifnet.if_reset as they are generally unused.
Change the parameter passed to if_watchdog to be a ifnet * rather than
a unit number. All of this is an attempt to move toward not needing an
array of softc pointers (which is usually static in size) to point to
the driver softc.
if_ed.c:
Changed some of the argument passing to some functions to make a little
more sense.
if_ep.c, if_vx.c:
Killed completely bogus use of if_timer. It was being set in such a way
that the interface was being reset once per second (blech!).
we're at it, eliminate obsolete exposure of `struct llinfo_arp' to
the world. (This dates back to when ARP entries were not stored in
the routing table, and there was no other way for the `arp' program
to read the whole table than to grovel around in /dev/kmem.)
a route. (This still doesn't work, but it doesn't panic now.) It looks
like there may be a number of incipient bugs in this code.
Also, get ready for the time when all IP gateway routes are cloning, which
is necessary to keep proper TCP statistics.
- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.
NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.
