def19aab78 Truly fix the lockup mentioned in 1.153. The PRISM hardware is not
capable of functioning in HostAP mode with a zero-length SSID, so
use " " if one is not set.

8b42c60645 Despite making the card not lock up, thae workaround from 1.153 didn't
actually make hostap mode work again.  Back it out while I try to find
a solution.

2cb7584b69 Fix wi(4)'s WI_RID_SCAN_RES ioctl (wicontrol -L). The wrong length
is computed, so the user thinks that for non-PRISM cards there are
more APs represented than exist.

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.

9bf40ede4a Replace the if_name and if_unit members of struct ifnet with new members
if_xname, if_dname, and if_dunit. if_xname is the name of the interface
and if_dname/unit are the driver name and instance.

This change paves the way for interface renaming and enhanced pseudo
device creation and configuration symantics.

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.

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.

	Maybe it should be table driven?

	ifconfig wi0 media DS/11Mbps still fails, but it fails before

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.
