tells that tun unit to prepend a four byte address family to packets
queued for tunread() and to expect a four byte address family at the
front of data received by tunwrite().
We queue any protocol received from the interface for tunread(), but
only accept INET, INET6, IPX and NETATALK from tunwrite(). There is
support for Xerox's NS stuff, but AFAICT config(8) doesn't ever
define NS.

so don't enforce the MTU as an MRU. Allow bidirectional ppp MTU
negotiation, by checking against a differnt figure for MRU.
Make it large enough for ATM frames at least.

Use the interface MTU instead of the constant when deciding what
packets to accept.
Allow using the SIOCSIFMTU ioctl (e.g. "ifconfig tun0 mtu XXX") to
set the MTU.

1/ increase the tun MTU from 1500 to 1600 to allow it to be used with
packets formatted according to RFC1490 and RFC1717
2/ allow the tsleep() when reading, to be interruptable by signals
so that one can now do:
od -xc </dev/tun0
to dump packets for debugging without getting hung.

Nice but not neccessary in 2.2

allow a tunnel interface to be openned even if it has no remote address yet.
this may be needed if you have used
route add default -interface tun0
where the remote end might not even HAVE a number (e.g. netcom links)

Story so fr:
1) PPP on-demand with static IP works.
2) PPP on-demand with dynamic IP says "Host is down" on any IP request
The problem is that tun driver check its READY state by *first* ifconfig address.
i.e.:
set ifaddr <addr> <addr2>
works (static IP) and
set ifaddr 0 <addr2>
not works (dynamic IP) because first address is equal 0.
Since tun is always POINTOPOINT interface, dst address is more meaningfull.
I change checking to second (dst) address in READY test.
PPP on-demand finally works.

- fill in and use ifp->if_softc
- use if_bpf rather than private cookie variables
- change bpf interface to take advantage of this
- call ether_ifattach() directly from Ethernet drivers
- delete kludge in if_attach() that did this indirectly

o Supporting SYNC SIO device (But need a device driver)
- add "set speed sync"
o Fixing bug for Predictor-1 function.
o Add new parameter that re-sent interval for set timeout commands.
o Improving RTT (Round Trip Time) and reducing processor time.
- Previous Timer service was using polling, and now using
SIGALRM ;-)
- A 0.94beta2 will not work correctly....
-- Follows are additinal feature not including 0.94beta2
o Support Proxy ARP
- add "enable/disable proxy" commands
o Marging common routine in CHAP/PAP.
o Enhancing LCP/IPCP log information.
o Support local Authfication connection on port 300x and tty.
- You can set up pair of your "hostname -s" and
password in ppp.secret. if either ppp.secret file nor
your hostname line don't exist, It will notify a message
and working as same as previous version.(Backword compatibility)
- If you did set up them, It's allow connection but nothing to do
except help and passwd command.
- add "passwd yourpasswd" commands
o Support afilter - keep Alive filter that a packet can send/receiving
according to ifilter/ofilter but doesn't count it as preventing idle
timer expires.
- Same syntax of other filters.
o Fixing bugs reported by current user for previous one. Thanks !!
