ca31d672e2 Install "show arptab" (db_show_arptab) in the ddb command tree.
Move prototype from netinet/if_inarp.h to ddb/db_interface.h.
Change function to have standard ddb parameters (though they're
ignored).

fc96443d15 New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
  resource allocation.
- Insertion and removal of callouts is constant time, important as
  this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.

f546d949b6 Decouple IP mtu for ARCnet devices from interface MTU.
This is important, because for most protocols, link level fragmentation is
used, but with different default effective MTUs. (e.g.: IPv4 default MTU
is 1500 octets, IPv6 default MTU is 9072 octets).

2aa9696fee Implement arp_drain(), which frees packets tied up in the arp cache if
mbufs are in short supply.
Create a (trivial) protocol domain for arp so that the drain routine will
be called from m_reclaim()

51867fc227 When sending an ARP reply, make sure to set the length of the outgoing
packet.

6b30aed924 Fix thinko of mine in previous. The source route info is not at m->m_data
after various m_adj()s have been done.  Kludge around this with a cheesy
macro that knows where the drivers put the mac header in the first mbuf.

XXX There should be a better way to do this.

0b3a9f9e00 Don't assume the Token-Ring source route is in the m_pktdat. Use
m_data instead.  This isn't a problem with ARP packets but is correct
way to this.

d8b8a41918 The rewrite of if_arp.c to work with the hashed interface address lists
(1.44) missed a test for the right interface, making some machines answer
to some bogus arp requests (like for WHO-HAS 127.0.0.1).

The quick patch in 1.46-1.47 does not work for so-called "unnumbered"
interfaces, that is, (point-to-point) interfaces that share their local
address with another (e.g., the Ethernet) interface.

We add a macro to in_var.h, to step (in the current implementation) through
the hash chain and fine more entries with the same address, and use that
in if_arp.c to find one which belongs to our interface.

07b064e02e New ARP system, supports IPv4 over any hardware link.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.
