Make serial ports more robust and reliable. Make non-console ports

o Introduce ping-pong receive buffers.
o Use DMA to copy characters directly into memory.
o Support baud rates other than 115200
o Use 1 stop bit when 1 stop bit is requested (otherwise 2 were used,
which caused dropped characters when received in bursts).
o Use 1.5 stop bits for 5-bit bytes, and 2 stop bits otherwise when 2
stop bits were requested.
o Actually update line parameters.
o Fix comments
o Move init into attach
o Tweaks to TX interrupt registers to get them reliable and non-storming.
o harvest data in ipend since the latency between it and the callback
was too long. This likely is how it should be, I don't know why I deferred
things to the callback before.
o disable all interrupts in console init. We don't want interrupts until
we turn on an ISR.
o cosmetic tweaks
o Automatically detect of the TIMEOUT interrupt is supported. If so, use
it so we get better CPU utilization. Otherwise do a character at a time
RX. Good news here is that it seems we have enough CPU and low enough
fast interrupt latency to do this reliably.
o Don't read USART_CR. It is a write-only register.
o start to implement bus_ioctl. Do BAUD now...

the mbuf chain. If we ever get a buggy caller, a bogus "off" should
be caught by the sanity check at the function entry. Null "m" here
means a very unusual condition of a totally broken mbuf chain (wrong
m_pkthdr.len or whatever), so we can just page fault later.

tree... John Baldwin noted that sio might pass values between probe
and attach via softc. It appears that sio does leave the hardware in
a known state after probing, so other drivers that try to probe might
leave it in a worse state. It doesn't seem to pass any data in softc,
however, that I could find... I think we should not be probing for
anything but nonPnP isa, but that's a change for another day.

except in places dealing with ifaddr creation or destruction; and
in such special places incomplete ifaddrs should never be linked
to system-wide data structures. Therefore we can eliminate all the
superfluous checks for "ifa->ifa_addr != NULL" and get ready
to the system crashing honestly instead of masking possible bugs.

a local 'semid' variable which was the array index and used uap->semid
as the original IPC id. During the kern_semctl() conversion those two
variables were collapsed into a single 'semid' variable breaking the
places that needed the original IPC ID. To fix, add a new 'semidx'
variable to hold the array index and leave 'semid' unmolested as the IPC
id. While I'm here, explicitly document that the (undocumented, at least
in semctl(2)) SEM_STAT command curiously expects an array index in the
'semid' parameter rather than an IPC id.

Previously, another thread could get a pointer to the
interface by scanning the system-wide list and sleep
on the global vlan mutex held by vlan_unconfig().
The interface was gone by the time the other thread
woke up.
In order to be able to call vlan_unconfig() on a detached
interface, remove the purely cosmetic bzero'ing of IF_LLADDR
from the function because a detached interface has no addresses.

Reorganise things to eliminate this, we now ensure that enc0 can not be
destroyed which as the benefit of no longer needing to lock in
ipsec_filter and ipsec_bpf. The cloner will create one interface during the
init so we can guarantee that encif will be valid before any SPD entries are
added to ipsec.

cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.
There are two possible reasons for there to be two different HWREVs:
1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
and the 8111B/8168B both use 0x38000000.
The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.
So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will
allow all devices to work, though if it turns out I'm wrong I may
need to change the ID strings
BCM5787 based NICs.
- Recognize BCM5703 B0 ASIC.
- Rewrite the jumbo capability matching macro, so that chips known

[*] I'm still not sure about this. Probably more corrections

OpenBSD. This driver seems to give a small performance increase, and
should lead to better maintainability in the future.
The nForce Ethernet-specific hack in sys/i386/xbox/xbox.c is still
required, judging from dev/nfe/if_nfe.c. The condition it hacks will
almost certainly only occur on XBOX-es anyway, so it is best left there.
