7a79cebfba Replay r286410. Change KPI of how device drivers that provide wireless
connectivity interact with the net80211 stack.

Historical background: originally wireless devices created an interface,
just like Ethernet devices do. Name of an interface matched the name of
the driver that created. Later, wlan(4) layer was introduced, and the
wlanX interfaces become the actual interface, leaving original ones as
"a parent interface" of wlanX. Kernelwise, the KPI between net80211 layer
and a driver became a mix of methods that pass a pointer to struct ifnet
as identifier and methods that pass pointer to struct ieee80211com. From
user point of view, the parent interface just hangs on in the ifconfig
list, and user can't do anything useful with it.

Now, the struct ifnet goes away. The struct ieee80211com is the only
KPI between a device driver and net80211. Details:

- The struct ieee80211com is embedded into drivers softc.
- Packets are sent via new ic_transmit method, which is very much like
  the previous if_transmit.
- Bringing parent up/down is done via new ic_parent method, which notifies
  driver about any changes: number of wlan(4) interfaces, number of them
  in promisc or allmulti state.
- Device specific ioctls (if any) are received on new ic_ioctl method.
- Packets/errors accounting are done by the stack. In certain cases, when
  driver experiences errors and can not attribute them to any specific
  interface, driver updates ic_oerrors or ic_ierrors counters.

Details on interface configuration with new world order:
- A sequence of commands needed to bring up wireless DOESN"T change.
- /etc/rc.conf parameters DON'T change.
- List of devices that can be used to create wlan(4) interfaces is
  now provided by net.wlan.devices sysctl.

Most drivers in this change were converted by me, except of wpi(4),
that was done by Andriy Voskoboinyk. Big thanks to Kevin Lo for testing
changes to at least 8 drivers. Thanks to pluknet@, Oliver Hartmann,
Olivier Cochard, gjb@, mmoll@, op@ and lev@, who also participated in
testing.

Still, drivers: ndis, wtap, mwl, ipw, bwn, wi, upgt, uath were not
tested. Changes to mwl, ipw, bwn, wi, upgt are trivial and chances
of problems are low. The wtap wasn't compilable even before this change.
But the ndis driver is complex, and it is likely to be broken with this
commit. Help with testing and debugging it is appreciated.

c68534f1d5 Update PCI drivers to no longer look at the MEMIO-enabled bit in the PCI
command register.  The lazy BAR allocation code in FreeBSD sometimes
disables this bit when it detects a range conflict, and will re-enable
it on demand when a driver allocates the BAR.  Thus, the bit is no longer
a reliable indication of capability, and should not be checked.  This
results in the elimination of a lot of code from drivers, and also gives
the opportunity to simplify a lot of drivers to use a helper API to set
the busmaster enable bit.

This changes fixes some recent reports of disk controllers and their
associated drives/enclosures disappearing during boot.

b032f27c36 Multi-bss (aka vap) support for 802.11 devices.
Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral).  Also there
no longer are separate wlan_scan* modules; this functionality is now
bundled into the wlan module.

13f4c340ae Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE and
IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to
ifnet.if_drv_flags.  Device drivers are now responsible for
synchronizing access to these flags, as they are in if_drv_flags.  This
helps prevent races between the network stack and device driver in
maintaining the interface flags field.

Many __FreeBSD__ and __FreeBSD_version checks maintained and continued;
some less so.

c009dcfdc2 Fix a couple of bugs in the resume handler. Don't call the if_init
function unless the device is configured up.  Without this fix, the
device ends up in the RUNNING state even though it is configured down.
Also, check the RUNNING flag before calling the if_start function, in
case the if_init function failed for one reason or another.

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.)

1bd2b5b4cd Integrate the hostap stuff that Thomas Skibo <skibo@packbell.net>
wrote.  This code was for 4.5-release, so I've ported it to -current

make access point the default.

More changes will be needed to get this actually working, but I wanted
to get a relatively pure baseline.  This doesn't seem to break what
works now.

a19c104dd2 Four fixes from NetBSD:
1) Properly detect the Symbol based cards (The 3Com Airconnect and their
   ilk) and only reset them *ONCE* ever.  This appears to make them work,
   but more testing is needed.  The tests that would wedge up my machine
   completely now appear to work, but I have not real access points
   handy.
2) Report both the Station firmware and the Primary firmware on Prism
   based cards.  On Lucent based cards, only report the station firmware
   since that's all it supports.  On symbol cards, report the symbol
   specific firmware name as its station firmware.
3) Better Prism 2.5 and 3 family names.  We really need to go table
   driven for this.
4) Workaround for bugs in Intersil's firmware is only needed for at most
   0.8.2 and earlier, since 0.8.3 and later appear to work.
