Merge r259393 from head:

Fix several panics when initialization of an ISA or PC-CARD device fails:

o Assign sc->an_dev in an_probe() (which isn't really a probe function in
the standard newbus sense) as we may need it for printing errors.
o Use device_printf() rather than if_printf() in an_reset() - this is
called from an_probe() long before the ifp structure is initialised
in an_attach().
o Initialize the ifp structure early in an_attach() as we use if_printf()
in cases where allocation of descriptors etc fails.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Use bus_*() rather than bus_space_*().

- Use device_printf() instead of printf() with an explicit unit number
in the PCI attach routine.
- Simplify PCI probe.
- Remove no-longer-used 'unit' from an_attach() parameters.

MFp4: Remove OLDCARD shims

MFp4: trivial KNF nits

Eliminate unused argument in PCMCIA_CARD macro.

Provide a backwards compatible way to have the extra macro by defining
PCCARD_API_LEVEL 5 before including pccarddevs for driver writers that
want/need to have the same driver on 5 and 6 with pccard attachments.

Fix disordering of pccarddevs.h noticed by bde. Also remove a few
redundant includes and fix some of the include disordering.

Submitted by: bde

Move to generating pccarddevs.h on the fly, both for the kernel and
the modules.

Also generate usbdevs.h automatically now, but a non-kernel file is
stopping that at the moment.

It turns out that the module dependency on pccard is in error. Since
there's not dependencies on pccard symboles, such a dependency is not
necessary. This means that drivers that have multiple attachments can
not drag bogus devices into the kernel at load time.

We can't (yet) do this with pci and isa. Drivers written for them
actually do seem to have symbols that depend on these busses'
implementation code.

ndis not touched until other things can be tested.

- Bump up the general and status RID sizes
- Clear out an_dma_vaddr on free so we can test to see if dma is
setup when the card is kldunloaded/kldloaded etc. only for MPI350
- Use a common detach like wi(4)
- Notify on RID read overflow and truncate this currently causes
a panic in -stable when the stack during an ifconfig an0 is done
with newer firmware
- Convert from UNLOCK/tsleep/LOCK to msleep. I thought I did that
a while ago.

Xircom Wireless Ethernet card is a rebadged Cisco 340, but with a
different vendor id/product id.

Use __FBSDID().
Also some minor style cleanups.

- Express hard dependencies on bus (pci, isa, pccard) and
network layer (ether).
- Don't abuse module names to facilitate ifconfig module loading;
such abuse isn't really needed. (And if we do need type information
associated with a module then we should make it explicit and not
use hacks.)

Don't lock in the attach routine. It isn't required. Register the
interrupt handler last. This gets rid of the sleep while locked
messages.

Make sure that pp_name is non-null before setting the device
description. This allows us to rely entirely on the CIS entries if
necessary...

Use __FBSDID rather than rcsid[].

an driver now needs wlan, so put the required explicit depends
into the source.

Add support for MPI-350 the mini-pci Cisco Aironet card. This needs more
work. The interface was gleaned from the Linux driver. Currently only
one RX & one TX buffer are used. Firmware support is not tested so for the
MPI-350 so it is disabled. Signal cache and monitor mode are not supported
yet. Signal cache is not supported since in encapsulation mode ethernet
frames are returned by the chip. LAN monitor mode support will be added
shortly. Thanks to Warner for the MPI-350 card he sent me.

Add support for RSSI map from PR kern/32880 which was incomplete. Enhanced
with the ability to select the cache mode of raw, dbm or per-cent.

Clean up Signal/Noise/Quality structures and units with help from
Marco Molteni.

Change flash to use a malloc'ed buffer when needed.

network interface driver changes:

o don't strip the Ethernet header from inbound packets; pass packets
up the stack intact (required significant changes to some drivers)
o reference common definitions in net/ethernet.h (e.g. ETHER_ALIGN)
o track ether_ifattach/ether_ifdetach API changes
o track bpf changes (use BPF_TAP and BPF_MTAP)
o track vlan changes (ifnet capabilities, revised processing scheme, etc.)
o use if_input to pass packets "up"
o call ether_ioctl for default handling of ioctls

Minor style problem I introduced recently

Hoist the Card/Card2 macros that I invented for the wi driver into
pccard layer and rename them PCMCIA_CARD and PCMCIA_CARD2 respectively
(note, this is being done with an eye towards NetBSD integreation so
it is easier to keep lists of cards between us and them in sync).

Use this in the an and wi drivers.

Add PC4500 and 350 for newer cards in this line.

Lots of style(9) related white space fixes. Mostly missing spaces
after if, for, while, switch, '{', and '}' plus a bunch of bogus
whitespace at the end of lines.

Currently, each wireless networking driver has it's own control program
despite the fact that most people want to set exactly the same settings
regardless of which card they have. It has been repeatidly suggested
that this configuration should be done via ifconfig. This patch
implements the required functionality in ifconfig and add support to the
wi and an drivers. It also provides partial, untested support for the
awi driver.

Catch up to header include changes:
- <sys/mutex.h> now requires <sys/systm.h>
- <sys/mutex.h> and <sys/sx.h> now require <sys/lock.h>

Catch up to moving headers:
- machine/ipl.h -> sys/ipl.h
- machine/mutex.h -> sys/mutex.h

Remember to assign an_dev to device_t before calling an_attach().

Convert the Aironet driver to use mutexes instead of spls.

Make all Ethernet drivers attach using ether_ifattach() and detach using
ether_ifdetach().

The former consolidates the operations of if_attach(), ng_ether_attach(),
and bpfattach(). The latter consolidates the corresponding detach operations.

Remove unloaded printf. We do this now in the newbus layer.

Add driver support for the Aironet 4500/4800 series wireless 802.11
NICs. (Finally!) The PCMCIA, ISA and PCI varieties are all supported,
though only the ISA and PCI ones will work on the alpha for now.
PCCARD, ISA and PCI attachments are all provided. Also provided an
ancontrol(8) utility for configuring the NIC, man pages, and updated
pccard.conf.sample. ISA cards are supported in both ISA PnP and hard-wired
mode, although you must configure the kernel explicitly to support the
hardwired mode since you have to know the I/O address and port ahead
of time.

Special thanks to Doug Ambrisko for doing the initial newbus hackery
and getting it to work in infrastructure mode.
