Add PCI .shutdown method so that we can disable the device during
shutdown or reboot. Without this, the reboot doesn't work well on
some platforms.

ipw2200 is able to detect when it's been hard-killed, but doesn't update
the core rfkill state or update userspace. Ensure that the state is updated,
allowing the rfkill core to notify userspace.

libipw unconditionally calls wiphy_unregister, but it's up to the driver
to register it in the first place. ipw2100 fails to do so. Add the necessary
glue code, and also ensure that rfkill statuses get set up appropriately.

(Augmented for proper wiphy_unregister placement. -- JWL)

Initiate the conversion of libipw to the new cfg80211 configuration API.

For now, leave CONFIG_IPW2200_PROMISCUOUS stuff alone.  Eventually
migrate it to cfg80211 when the add/del/change_virtual_intf methods
are implemented.

(v2: Fix unconditional wiphy_unregister in libipw which was causing
     problems for ipw2100, somewhat based on prior attempted fix
     by Zhu Yi <yi.zhu@intel.com>.  Previously both original version of
     this patch and Zhu Yi's fix attempt were reverted due to
     discovery of regressions. -- JWL)

This reverts commit b8ecd988.

Due to poor API call balancing by me, this commit not only broke ipw2200
if it can't find it's firmware, it broke ipw2100 basically anytime you
removed the module.  At this point in the cycle, let's just put it back
to a sane state and try again next time...

Subject: BUG: oops when "rmmod ipw2200"

This happened on wireless-testing v2.6.32-rc6-41575-g5e68bfb. I
modprobed ipw2200, put it into monitor mode, used tshark a while to
monitor, then I stopped tshark, "ifconfig eth2 down" and finally
"rmmod ipw2200", and voila:

For non-monitor interfaces, the syntax for alloc_ieee80211/free_80211
is wrong. Because alloc_ieee80211 only creates (wiphy_new) a wiphy, but
free_80211() does wiphy_unregister() also. This is only correct when
the later wiphy_register() is called successfully, which apparently
is not the case for your fw doesn't exist one.

Refactor wext to
 * split out iwpriv handling
 * split out iwspy handling
 * split out procfs support
 * allow cfg80211 to have wireless extensions compat code
   w/o CONFIG_WIRELESS_EXT

After this, drivers need to
 - select WIRELESS_EXT	- for wext support
 - select WEXT_PRIV	- for iwpriv support
 - select WEXT_SPY	- for iwspy support

except cfg80211 -- which gets new hooks in wext-core.c
and can then get wext handlers without CONFIG_WIRELESS_EXT.

Wireless extensions procfs support is auto-selected
based on PROC_FS and anything that requires the wext core
(i.e. WIRELESS_EXT or CFG80211_WEXT).

Bartlomiej Zolnierkiewicz reported an atomic order-6 allocation failure
for ipw2200 firmware loading in kernel 2.6.30. High order allocation is
likely to fail and should always be avoided.

The patch fixes this problem by replacing the original order-6
pci_alloc_consistent() with an array of order-1 pages from a pci pool.
This utilized the ipw2200 DMA command blocks (up to 64 slots). The
maximum firmware size support remains the same (64*8K).

This patch fixes bug http://bugzilla.kernel.org/show_bug.cgi?id=14016

The result of container_of should not be NULL.  In particular, in this case
the argument to the enclosing function has passed though INIT_WORK, which
dereferences it, implying that its container cannot be NULL.

A simplified version of the semantic patch that makes this change is as
follows:
(http://www.emn.fr/x-info/coccinelle/

)

// <smpl>
@@
identifier fn,work,x,fld;
type T;
expression E1,E2;
statement S;
@@

static fn(struct work_struct *work) {
  ... when != work = E1
  x = container_of(work,T,fld)
  ... when != x = E2
- if (x == NULL) S
  ...
}
// </smpl>

This patch converts the remaining occurences of raw return values to their
symbolic counterparts in ndo_start_xmit() functions that were missed by the
previous automatic conversion.

Additionally code that assumed the symbolic value of NETDEV_TX_OK to be zero
is changed to explicitly use NETDEV_TX_OK.

Convert magic values 1 and -1 to NETDEV_TX_BUSY and NETDEV_TX_LOCKED respectively.

0 (NETDEV_TX_OK) is not changed to keep the noise down, except in very few cases
where its in direct proximity to one of the other values.

net: fix network drivers ndo_start_xmit() return values (part 3)

Fix up wireless drivers that return an errno value to qdisc_restart(), causing
qdisc_restart() to print a warning an requeue/retransmit the skb.

- airo: transmission not implemented for chip, intention is to free and abort
- ipw2200: transmission not implemented for promiscous mode, intention is to
           drop
- prism54: intention is to drop
- wl3501_cs: intention appears to be to drop
- zd1201: error counter indicates intention is to drop

All drivers compile tested.

In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device.  Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used.  These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Since both ipw2100 and ipw2200 are already converted to new
net_device_ops this code is useless.
