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.

initialized, it might equal &iproute by chance, causing a panic
when rtfree() is then mistakenly called.

number, it can differ from the sequence number being tested (for packets
without payload), and both matter in explaining why a packet mismatched.

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.

ifp0->if_link_state == LINK_STATE_UP to handle the new half/full
duplex link states. i forgot to commit these snippets before.

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.

but the really bad description of the diff made this way more complicated
then needed. pls plz, when sending in diffs, describe properly what they
do and why!

duplex state without depending on the ifmedia ioctl which can't be
called in the kernel without process context.

ok claudio@, looks fine henning@

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
part was missing) when rtableid on the rule is nonzero.

be imported into pfctl. This is a precursor to separating ruleset parsing
from loading in pfctl, and tons of good things will come from it.
2 minor changes aside from cut-n-paste and #define portability magic:
- instead of defining the global pf_main_ruleset, define pf_main_anchor
(which contains the pf_main_ruleset)
- allow pf_find_or_create_ruleset() to return the pf_main_ruleset if it's
passed an empty anchor name.

for now, only allow pflog0 to be created.
keep an array of ifps to the pflog interfaces with the unit # as index for
fast access.
if pflog0 does not exist, no logging is done (just like if it is down).
on machines without pf enabled, this makes the pflog0 interface go away,
on machines with pf, rc sets up pflog0 and starts pflogd, no change there.

the anchor, terminate ruleset evaluation when stepping out of the anchor.
This means that if you absolutely want the anchor to be terminal, you
probably want to use a 'block all' or 'pass all' rule at the start of the
anchor.

for equality (ip_tos == x). for priority queue assignment, compare AND-wise
(ip_tos & IPTOS_LOWDELAY). this matters mostly for cases where the reserved
bits in ip_tos are used (RFC791, 1349) and more than a single bit is set.
