2009-11-13Revert "libipw: initiate cfg80211 API conversion"John W. Linville
This reverts commit b8ecd988b1670035a05035c553c08331214d6603. 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... Signed-off-by: John W. Linville <linville@tuxdriver.com>

This reverts commit e6c5fc53d0f44a772398402ee8a1879818e42b4e. Based on this regression report: Date: Thu, 05 Nov 2009 15:59:16 +0100 From: Holger Schurig <holgerschurig@gmail.com> To: linux-wireless@vger.kernel.org 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: [ 917.189620] ------------[ cut here ]------------ [ 917.189717] kernel BUG at net/wireless/core.c:543!

2009-10-30ipw2200: fix oops on missing firmwareZhu Yi
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.

2009-08-28libipw: initiate cfg80211 API conversionJohn W. Linville
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. Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-08-28libipw: switch from ieee80211_* to libipw_* naming policyJohn W. Linville
This eliminates the dual definition of ieee80211_channel (and possibly others), further clarifying who defines what and paving the way for inclusion of cfg80211.h. Signed-off-by: John W. Linville <linville@tuxdriver.com>

2009-02-27ipw2x00: age scan results on resumeDan Williams
Scanned BSS entries are timestamped with jiffies, which doesn't increment across suspend and hibernate. On resume, every BSS in the scan list looks like it was scanned within the last 10 seconds, irregardless of how long the machine was actually asleep. Age scan results on resume with the time spent during sleep so userspace has a clue how old they really are. Signed-off-by: Dan Williams <dcbw@redhat.com> Signed-off-by: John W.

2008-11-21net/ieee80211 -> drivers/net/ipw2x00/libipw_* renameJohn W. Linville
The old ieee80211 code only remains as a support library for the ipw2100 and ipw2200 drivers. So, move the code and rename it appropriately to reflects it's true purpose and status. Signed-off-by: John W. Linville <linville@tuxdriver.com>
