186b491745 net/wireless: ipw2x00: remove unused libipw_measurement_report struct
and all referenced structs and corresponding enums because the driver
does not use it.

Note: keep libipw_info_element struct since it is still in use.

27ae60f8f7 ipw2x00: replace "ieee80211" with "libipw" where appropriate
"ieee80211" was the old name of the common library for ipw2100 and
ipw2200.  It was renamed to "libipw", but some occurrences of the old
name remained.

Rename alloc_ieee80211() to alloc_libipw() and free_ieee80211() to
free_libipw().  Adjust comments and label names.  Change prefixes in
diagnostic messages.

Keep /proc/net/ieee80211 under the original name to avoid breaking user
interface.

Move the affected EXPORT_SYMBOL macros to their proper places.

8e59340e4f libipw: split ieee->networks into small pieces
The ieee->networks consists of 128 struct libipw_network entries. If
we allocate this chunk of memory altogether, it ends up with an
order 4 page allocation. High order page allocation is likely to fail
on system high load. This patch splits the big chunk memory allocation
into small pieces, each is 344 bytes, allocates them with 128 times.

The patch fixed bug http://bugzilla.kernel.org/show_bug.cgi?id=14989

a3caa99e6c libipw: initiate cfg80211 API conversion (v2)
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)

8cc3174ef9 Revert "libipw: initiate cfg80211 API conversion"
This reverts commit b8ecd988b1.

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:

e6c5fc53d0 ipw2200: fix oops on missing firmware
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.

d0cf9c0dad wireless: convert drivers to netdev_tx_t
Mostly just simple conversions:
  * ray_cs had bogus return of NET_TX_LOCKED but driver
    was not using NETIF_F_LLTX
  * hostap and ipw2x00 had some code that returned value
    from a called function that also had to change to return netdev_tx_t
