- Add an rm_assert() supporting various lock assertions similar to other
locking primitives. Because rmlocks track readers the assertions are
always fully accurate unlike rw_assert() and sx_assert().
- Flesh out the lock class methods for rmlocks to support sleeping via
condvars and rm_sleep() (but only while holding write locks), rmlock
details in 'show lock' in DDB, and the lc_owner method used by
dtrace.
- Add an internal destroyed cookie so that API functions can assert
that an rmlock is not destroyed.
- Make use of rm_assert() to add various assertions to the API (e.g.
to assert locks are held when an unlock routine is called).
- Give RM_SLEEPABLE locks their own lock class and always use the
rmlock's own lock_object with WITNESS.
- Use THREAD_NO_SLEEPING() / THREAD_SLEEPING_OK() to disallow sleeping
while holding a read lock on an rmlock.

This is an extended version of ipv4_addr_IF which supports both IPv4 and
IPv6, and multiple range specifications. To avoid to generate too many
addresses, the maximum number of the generated addresses is currently
limited to 31.
- Add $ifconfig_IF_aliases, which accepts multiple IP aliases in a variable.
- ipv6_prefix_IF now supports !/64 prefix length. In addition to the old
64-bit format (2001:db8:1:1), a full 128-bit format like 2001:db8:1:1::/64
is supported.
- Replace ifconfig command with $IFCONFIG_CMD variable to support
a dry-run mode in the future.
- Remove IP aliases before removing all of IPv4 addresses when doing
"rc.d/netif down".
- Add a DAD wait to network6_getladdr() because it is possible to fail to
configure an EUI64 address when ipv6_prefix_IF is specified.
A summary of the supported ifconfig_* variables is as follows:
# IPv4 configuration.
ifconfig_em0="inet 192.168.0.1"
# IPv6 configuration.
ifconfig_em0_ipv6="inet6 2001:db8::1/64"
# IPv4 address range spec. Now deprecated.
ipv4_addr_em0="10.2.1.1-10"
# IPv6 alias.
ifconfig_em0_alias0="inet6 2001:db8:5::1 prefixlen 70"
# IPv4 alias.
ifconfig_em0_alias1="inet 10.2.2.1/24"
# IPv4 alias with range spec w/o AF keyword (backward compat).
ifconfig_em0_alias2="10.3.1.1-10/32"
# IPv6 alias with range spec.
ifconfig_em0_alias3="inet6 2001:db8:20-2f::1/64"
# ifconfig_IF_aliases is just like ifconfig_IF_aliasN.
ifconfig_em0_aliases="inet 10.3.3.201-204/24 inet6 2001:db8:210-213::1/64 inet 10.1.1.1/24"
# IPv6 alias (backward compat)
ipv6_ifconfig_em0_alias0="inet6 2001:db8:f::1/64"
# IPv6 alias w/o AF keyword (backward compat)
ipv6_ifconfig_em0_alias1="2001:db8:f:1::1/64"
# IPv6 prefix.
ipv6_prefix_em0="2001:db8::/64"

optionally start the traversal from a previously found element by passing the
element in as "var". Passing a NULL "var" retains the same semantics as the
regular FOREACH macros.
Kudos to phk for suggesting the "FROM" suffix instead of my original proposal.

{,ipv6_}static_routes and rc.d/routing. For example:
static_routes="foo bar:em0"
route_foo="-net 10.0.0.0/24 -gateway 192.168.2.1"
route_bar="-net 192.168.1.0/24 -gateway 192.168.0.2"
At boot time, all of the static routes are installed as before.
The differences are:
- "/etc/rc.d/netif start/stop <if>" now configures static routes
with :<if> if any.
- "/etc/rc.d/routing start/stop <af> <if>" works as well. <af> cannot be
omitted when <if> is specified, but a keyword "any" or "all" can be used
for <af> and <if>.

This driver requires microcode which is available in FreeBSD ports:
net/urtwn-firmware-kmod.
Hiren ported the urtwn(4) man page from OpenBSD and Glen just commited a port
for the firmware.
TODO:
- 802.11n support
- Stability fixes - the driver can sustain lots of traffic but has trouble
coping with simultaneous iperf sessions.
- fix debugging

The NTB allows you to connect two systems with this device using a PCI-e
link. The driver is made of two modules:
- ntb_hw which is a basic hardware abstraction layer for the device.
- if_ntb which implements the ntb network device and the communication
protocol.
The driver is limited at the moment to CPU memcpy instead of using DMA, and
only Back-to-Back mode is supported. Also the network device isn't full
featured yet. These changes will be coming soon. The DMA change will also
bring in the ioat driver from the project branch it is on now.
This is an initial port of the GPL/BSD Linux driver contributed by Jon Mason
from Intel. Any bugs are my contributions.

'install' since it breaks buildworld after the introduction and
use of 'install -l' in r245752. Overriding INSTALL causes
/usr/bin/install to be used instead of the proper
/usr/src/tools/install.sh which handles the new flag.
