- Use unit2minor() and minor2unit() to generate minor numbers to support
unit numbers higher than 255.
- Use simple string operations on the 'names' array rather than hard-coded
constants and switch statements so that more ptys can be added by simply
expanding the 'names' array.

TODO:
Convert to per cpu variables linkerset as soon as it is available.
Optimize UP (single processor) case.
* When installing updates, make sure that securelevel <= 0. Otherwise
we can't remove the schg flag from files.
* When preparing to download updates, check to see if we already have
them sitting in the /files/ directory. This saves bandwidth if users
run "freebsd-update fetch" more than once without installing updates
in between.
While I'm here, bump the copyright date.

- Patch registers CR47 and CR157 on devices that require it.
- Fix power calibration setting on ZD1211B.
Obtained from: OpenBSD
- Fix multicast transfer by properly reprogram multicast global
hash table, which in turns fix promiscuous mode and IPv6
autoconfiguration / local networking.

I've tried to move md(4) to use geom_disk class, like real disks do, but
this requires major rework of some of the existing features such as
configuration dumping for example. Therefore just putting devstat support
directly into md(4) seems to be optimal solution.
Now you can see md(4) stats in `systat -vm' again.

present on the MacBook, MacBook Pro, and Intel MacMini.
This driver exports information via sysctl in its private sysctl tree
dev.asmc.*. You can get information about temperatures, fan speeds, the
keyboard light sensor and the Sudden Motion Sensor (SMS).
The SMS is very useful to park the disk heads when the laptop is
moved. Basically, the SMS is setup so that, under movement, we get an
interrupt on irq 6 and a devd notification is sent.

LINUX_SIOCGIFCOUNT just returns 0 since it is not implemented in the
Linux 2.6.16.
LINUX_SIOCGIFINDEX/LINUX_SIOGIFINDEX are mapped to the FreeBSD native
SIOCGIFINDEX.

2) Alter packet flow inside dummynet: allow certain packets to bypass
dummynet scheduler. Benefits are:
- lower latency: if packet flow does not exceed pipe bandwidth, packets
will not be (up to tick) delayed (due to dummynet's scheduler granularity).
- lower overhead: if packet avoids dummynet scheduler it shouldn't reenter ip
stack later. Such packets can be fastforwarded.
- recursion (which can lead to kernel stack exhaution) eliminated. This fix
long existed panic, which can be triggered this way:
kldload dummynet
sysctl net.inet.ip.fw.one_pass=0
ipfw pipe 1 config bw 0
for i in `jot 30`; do ipfw add 1 pipe 1 icmp from any to any; done
ping -c 1 localhost
3) Three new sysctl nodes are added:
net.inet.ip.dummynet.io_pkt - packets passed to dummynet
net.inet.ip.dummynet.io_pkt_fast - packets avoided dummynet scheduler
net.inet.ip.dummynet.io_pkt_drop - packets dropped by dummynet
P.S. Above comments are true only for layer 3 packets. Layer 2 packet flow
is not changed yet.
