08daf78765 Eliminate bogus seatbelt in wi_cmd. This may have been appropriate
for the spl-era locking, but now that we can have multiple, concurrent
interrupts for multiple wi devices, having a global check to make sure
at most one of them was in wi_cmd no longer makes sense.

b5c9941514 Clarify/fix handling of the current channel:
o add ic_curchan and use it uniformly for specifying the current
  channel instead of overloading ic->ic_bss->ni_chan (or in some
  drivers ic_ibss_chan)
o add ieee80211_scanparams structure to encapsulate scanning-related
  state captured for rx frames
o move rx beacon+probe response frame handling into separate routines
o change beacon+probe response handling to treat the scan table
  more like a scan cache--look for an existing entry before adding
  a new one; this combined with ic_curchan use corrects handling of
  stations that were previously found at a different channel
o move adhoc neighbor discovery by beacon+probe response frames to
  a new ieee80211_add_neighbor routine

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.

d365f9c760 Cleanup beacon/listen interval handling:
o separate configured beacon interval from listen interval; this
  avoids potential use of one value for the other (e.g. setting
  powersavesleep to 0 clobbers the beacon interval used in hostap
  or ibss mode)
o bounds check the beacon interval received in probe response and
  beacon frames and drop frames with bogus settings; not clear
  if we should instead clamp the value as any alteration would
  result in mismatched sta+ap configuration and probably be more
  confusing (don't want to log to the console but perhaps ok with
  rate limiting)
o while here up max beacon interval to reflect WiFi standard

584d11ee54 When the MAC address is reported all zeros, then error is necessarily
0.  This means that we 'succeed' the attach, even after we've freed
the internal data bits.  This leads to a panic when you eject the card
with this problem.

Set error = ENXIO in the mac read zeros case.

fc74a9f93a Stop embedding struct ifnet at the top of driver softcs. Instead the
struct ifnet or the layer 2 common structure it was embedded in have
been replaced with a struct ifnet pointer to be filled by a call to the
new function, if_alloc(). The layer 2 common structure is also allocated
via if_alloc() based on the interface type. It is hung off the new
struct ifnet member, if_l2com.

This change removes the size of these structures from the kernel ABI and
will allow us to better manage them as interfaces come and go.

Other changes of note:
 - Struct arpcom is no longer referenced in normal interface code.
   Instead the Ethernet address is accessed via the IFP2ENADDR() macro.
   To enforce this ac_enaddr has been renamed to _ac_enaddr.
 - The second argument to ether_ifattach is now always the mac address
   from driver private storage rather than sometimes being ac_enaddr.

8d2ad0b460 The two PLANEX cards listed in pccarddevs, identified only by their
CIS, weren't actually used anywhere (other than the generic PC Card
code when certain variables are defined).  They aren't used in NetBSD
either.  Make things simpler by removing them.  Change PLANEX_2 to
PLANEX and tweak wi and owi to use that instead.  The PLANEX id seems
to actually be pci ID assigned to planex, not its pcmcia id.  Ooops.
I don't know if this is a reporting error from where this entry came
from, or if it is a mistake on PLANEX's part.  I suspect the latter,
as ACTIONTEC and NEWMEDIA made the same mistake (although new media
may be because it uses an advansys chip inside).  Make a note of this
in the file.  The 0xc entires may be JEITA assigned, so note that as
well.

fbfb97942e 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.

86e011b3e8 On my ZoomAir-branded Intersil PRISM2 cards, if you try to set the
operating mode to HostAP, the card will lock up indefinitely (but
the wi(4) driver can recover if you eject the card).  The problem is
that the card needs to be "reset" in a way before you even change the
media to hostap.  In practice this isn't as noticeable because you
probably do some operation beforehand which prevents the lock-up
before you enable hostap mode.

e.g.:
"ifconfig wi0 up media autoselect mediaopt hostap" will lock up
(if you just inserted the card).
"ifconfig wi0 up ssid foo media autoselect mediaopt hostap" won't lock up.

0a915fad5d MFp4 changes to fix locking issues and correct reference
count handling of station entries in hostap mode:

Input path:

o driver is now expected to find the node associated with the
  sender of a received frame; use ic_bss if none is located
o driver passes the (referenced) node into ieee80211_input for
  use within the wlan module and is responsible for cleaning up
  on return
o the antenna state is no longer passed up with each frame; this
  is now considered driver-private state and drivers are responsible
  for keeping it in the driver-private part of a node

Output path:

Revamp output path for management frames to eliminate redundant
locking that causes problems and to correct reference counting
bogosity that occurs when stations are timed out due to inactivity
(in AP mode).  On output the refcnt'd node is stashed in the pkthdr's
recvif field (yech) and retrieved by the driver.  This eliminates
an unref/ref scenario and related node table unlock/lock due to the
driver looking up the node.  This is particularly important when
stations are timed out as this causes a lock order reversal that
can result in a deadlock.  As a byproduct we also reduce the overhead
for sending management frames (minimal).  Additional fallout from
this is a change to ieee80211_encap to return a refcn't node for
tieing to the outbound frame.  Node refcnts are not reclaimed until
after a frame is completely processed (e.g. in the tx interrupt
handler).  This is especially important for timed out stations as
this deref will be the final one causing the node entry to be
reclaimed.

Additional semi-related changes:
o replace m_copym use with m_copypacket (optimization)
o add assert to verify ic_bss is never free'd during normal operation
o add comments explaining calling conventions by drivers for frames
  going in each direction
o remove extraneous code that "cannot be executed" (e.g. because
  pointers may never be null)

f6b1c44d1f Mega busdma API commit.
Add two new arguments to bus_dma_tag_create(): lockfunc and lockfuncarg.
Lockfunc allows a driver to provide a function for managing its locking
semantics while using busdma.  At the moment, this is used for the
asynchronous busdma_swi and callback mechanism.  Two lockfunc implementations
are provided: busdma_lock_mutex() performs standard mutex operations on the
mutex that is specified from lockfuncarg.  dftl_lock() is a panic
implementation and is defaulted to when NULL, NULL are passed to
bus_dma_tag_create().  The only time that NULL, NULL should ever be used is
when the driver ensures that bus_dmamap_load() will not be deferred.
Drivers that do not provide their own locking can pass
busdma_lock_mutex,&Giant args in order to preserve the former behaviour.

sparc64 and powerpc do not provide real busdma_swi functions, so this is
largely a noop on those platforms.  The busdma_swi on is64 is not properly
locked yet, so warnings will be emitted on this platform when busdma
callback deferrals happen.

If anyone gets panics or warnings from dflt_lock() being called, please
let me know right away.

3cd0b4fd09 Return support needed by dstumbler:
o add back rx monitor support
o make WI_RID_SCAN_RES DTRT
o fix a bug handling zero-length RID requests (used by dstumbler to set
  a zero-length SSID)
o make RID_SCAN_REQ DTRT
o add back WI_RID_OWN_SSID
o fix wi_scan_ap to take a channel mask and txrate (for prism cards)

These changes fix dstumbler -o (monitor mode).  A minor change to dstumbler
is needed to get normal AP scanning mode to work right; this is preferred to
modifying the driver.

9b1b4524e6 As a workaround for the latest problems, don't init hermes cards more
than once.  This appears to work around the hanging issues, at the
expense of warnings about bad RID allocations.  I'm not sure this is a
permanant workaround, but does appear to help in the tests that I've
done here.

854cb5a41a Don't hold a driver lock across bus_teardown_intr. Jhb points out
that one cannot generally hold a lock and call bus_teardown_intr.
This is race free with wi_intr because bus_teardown_intr won't allow
wi_intr to be called after it returns.

# jeff hsu points out that there might be a race between this unlock
# and wi_start.  While that may be true also, it won't impact this commit.

a4da74c1d9 Make 2/3 of my symbol cards work again. The 3rd symbol card card has
firmware 1.50.12, but 2.20.1 and 3.10.4 work.  The 1.50.12 card gets
past doing dhclient, but hangs on transmit a little after the ip
address is set.  The 1.50.12 card has always been 'cranky' and Bill
Paul's tearing it apart at FreeBSD '99 hasn't helped.

sc_reset and sc_enable are subtlely different things.  sc_reset means
exactly "WI_CMD_INI has happened."  sc_enabled means "WI_CMD_ENABLE
has been sent to the card without a WI_CMD_DISABLE following."  This
is a little different than what they mean on NetBSD (where both of
these concepts are comingled).  NetBSD will try to only enable symbol
cards once, while FreeBSD only sends the WI_CMD_INI once.

Also, only try once to reset the card on a symbol.

This makes the lucent cards no worse than before, but apparently not
much better either.  I got fewer hangs in my testing than I have in
the past, but I don't know if it is statistically significant or not.

b899d58ee4 Use the new _ND macros to not include the description strings. If any
of the entries have a description, we'll use that to override the
description that the pccard layer generates for us.

This saves about 930 bytes in the module, so I feel it won't hurt the
crowded boot disks....

Change 27224 by imp@imp_hammer on 2003/03/22 00:16:22
	Put what I think are the correct TX RATE translation tables

	Maybe it should be table driven?

	ifconfig wi0 media DS/11Mbps still fails, but it fails before
	we even get to the txrate stuff, so other things are wrong.

Change 27225 by imp@imp_hammer on 2003/03/22 00:45:11
	Default ic_fixed_rate to -1.  This is the same thing as autoselect.
	There really should be a #define for this...

0e630ee24b o Lucent cards don't seem to like multiple buffers for tx. Use only
one tx buffer for these cards.  The old driver only used one.  We use
  1 for symbol, and 3 for prism cards.
o Don't do the maximum loops thing in the ISR.  In fact, revert to the
  old interrupt handler.  Lucent cards don't seem to work too well if
  you don't disable/enable interrupts from the card in the ISR.

Between these two changes, Lucent cards suck less.  They work in
autoselect mode only.  And seem to get 1Mbps or 2Mbps only.  Setting a
specific media speed doesn't work, and I've had a few issues even with
these patches.  They turn a former brick into a nearly useful card.

These patches work on the prism 2 and 2.5 PC Card cards that I have.
I've not tested this on PCI cards.  I suspect, but couldn't find
proof, that they were the reason that the ISR was changed so radically
from its FreeBSD roots in NetBSD.  We might need to have a variant ISR
if so.
