Previously the descriptor was locked only after
an interface is set, leading to a race condition.

via TUNSIFINFO. ppp(8) was happily clearing the RUNNING flag and so all
incomming packets where dropped. Issue reported by irix <at> ukr <dot> net.
While there check that the mtu is in a valid range -- stolen from SIOCSIFMTU
case.

this allows an atomic read and reset counters, instead of read, reset in a
later ioctl and lose everything in between.
use the previously unused of pr->action. When it is set to PF_GET_CLR_CNTR,
the ioctl requires write permissions and counters are reset after they have
been copied out to userland.
obsoletes DIOCCLRRULECTRS, which only works for the main ruleset, but not
within anchors (yeah, that's how it all started)
ok dhartmei, mcbride and theo agree as well

ip6_dst (i'm bit skeptical about checksumming when the box is not the
final destination).
drop IPv6 jumbograms, as it could cause various funny symptoms due to
ip6_plen being 0 (yup, we should properly handle it instead).

- if the interface was auto-created by opening a /dev/tun* device it will
auto-destroy on close. This is comparable to ifconfig tun0 destroy and
will remove all routes and addresses associated with the interface.
- if the interface was created by ifconfig(8) or hostname.if(5) the interface
is persistent -- it is just marked as not running. Especially routes are no
longer removed when the interface is closed. This is useful for static
setups like the server side of a ssh vpn or static qemu session.
This behaviour is more logic then the half done cleanup that is currently done.

unicast reverse path forwarding (URPF) check drops packets coming in
on an interface other than that which holds the route back to the
packet's source address. this caused problems with routes bound to a
carp interface instead of the underlying interface. this diff
validates the underlying carpdev if the route is bound to a carp
interface.

P2P is commonly used in relation to peer to peer networks, PTP is used
in various protocols for layer 2 point to point links (ie., full
duplex ethernet links).
note that the newly added brconfig commands [-]p2p and [-]autop2p will
change to [-]ptp and [-]autoptp.

by Andrew Thompson (thompsa@freebsd.org). The local changes include
adoption to our bridge code, reduced stack usage and many other bits.
If stp is enabled, RSTP will now be used by default.
Thanks for help from Andrew.

phase 2 traffic. this allows policy-based filtering of encrypted and
unencrypted ipsec traffic with pf(4). see ipsec.conf(5) and
isakmpd.conf(5) for details and examples.
this is work in progress and still needs some testing and feedback,
but it is safe to put it in now.

ifp->if_link_state instead of calling the ifmedia ioctl. this is safe
in timeouts without process context and allows to use bridge stp with
usb ethernet devices now.
figured out and tested by Stuart Henderson, closes pr 5304.

we need to do so whenever we do have a (pf) tag != 0 on the state OR (that
