2009-01-29nl80211: New command for adding extra IE(s) into management framesJouni Malinen
A new nl80211 command, NL80211_CMD_SET_MGMT_EXTRA_IE, can be used to add arbitrary IE data into the end of management frames. The interface allows extra IEs to be configured for each management frame subtype, but only some of them (ProbeReq, ProbeResp, Auth, (Re)AssocReq, Deauth, Disassoc) are currently accepted in mac80211 implementation. This makes it easier to implement IEEE 802.11 extensions like WPS and FT that add IE(s) into some management frames. In addition, this can be useful for testing and experimentation purposes.

In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using 'ahp->ah_curani' unconditionally, and it will cause a NULL pointer dereference on AR9100.

2009-01-29ath9k: fix ar5416Addac_9100 valuesGabor Juhos
Writing the register at offset 0x98c4 causes a deadlock on the AR913x SoCs. Although i don't have detailed knowledge about these registers, but if i change the register offset according to the 'ar5416Addac' table, it works.

2009-01-29iwl3945: report killswitch changes even if the interface is downHelmut Schaa
Currently iwl3945 is not able to report hw-killswitch events while the interface is down. This has implications on user space tools (like NetworkManager) relying on rfkill notifications to bring the interface up once the wireless gets enabled through a hw killswitch. Thus, enable the device already in iwl3945_pci_probe instead of iwl3945_up and poll the CSR_GP_CNTRL register to update the killswitch state every two seconds. The polling is only needed on 3945 hardware as this adapter does not use interrupts to signal rfkill changes to the driver (in case no firmware is loaded). The firmware loading is still done in iwl3945_up. Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Acked-by: Samuel Ortiz <samuel.ortiz@intel.com> Signed-off-by: John W.

2009-01-29ath5k: discard 11g caps if reported by an ar5211 eepromHelmut Schaa
At least one ar5211 card (GIGABYTE GN-WLMA101, 168c:0012 subsystem 1458:e800) reports itself as 11g capable which seems to be a bug in the eeprom. initvals.c assumes that ar5211 is only 11b capable and thus refuses to initialize this card. Hence this patch changes the probing for 11g capabilities to discard 11g capabilities for ar5211 cards which allows this specific card to work fine in 11b and 11a modes.
