best we can if that fails.

become available. This may significantly reduce overhead by reducing
the number of unnecessary wakeups issued whenever the framework becomes
idle.
Annotate that we still signal the CV more than necessary and should
fix this.

Redo the checking for 2.6 emulation. We now cache the value of
use26 and replace calls to linux_get_osrelease() + parsing with
a call to linux_use26(). Typical path is lockless now.
Pointed out by: kib
This allows to ship RELENG_7_0 with a default osrelease of 2.4.2 and the
possibility to enable 2.6.x emulation without the possible performance
impact of the previous version of the check.

interpreted $command. Some "portable" sofware packages use such a
line to skip the task of figuring out the absolute pathname of the
interpreter at install time, e.g.:
#!/usr/bin/env python
It is insecure, but a popular book on Python seems to have advised
it to a wide audience. Hence a number of such scripts in the ports,
mostly written in Python.

for the rc.subr internals. Most scripts can be fixed by just
declaring _foo symbols as local: few scripts actually need them to
be global.

With the second (and last) part of my previous Summer of Code work, we get:
-ipfw's in kernel nat
-redirect_* and LSNAT support
General information about nat syntax and some examples are available
in the ipfw (8) man page. The redirect and LSNAT syntax are identical
to natd, so please refer to natd (8) man page.
To enable in kernel nat in rc.conf, two options were added:
o firewall_nat_enable: equivalent to natd_enable
o firewall_nat_interface: equivalent to natd_interface
Remember to set net.inet.ip.fw.one_pass to 0, if you want the packet
to continue being checked by the firewall ruleset after being
(de)aliased.
NOTA BENE: due to some problems with libalias architecture, in kernel
nat won't work with TSO enabled nic, thus you have to disable TSO via
ifconfig (ifconfig foo0 -tso).

access plus timers. This makes the code
more portable and able to change out the
mbuf or timer system used more easily ;-)
b) removal of all use of pkt-hdr's until only
the places we need them (before ip_output routines).
c) remove a bunch of code not needed due to <b> aka
worrying about pkthdr's :-)
d) There was one last reorder problem it looks where
if a restart occur's and we release and relock (at
the point where we setup our alias vtag) we would
end up possibly getting the wrong TSN in place. The
code that fixed the TSN's just needed to be shifted
around BEFORE the release of the lock.. also code that
set the state (since this also could contribute).
