2012-03-13mac80211: rename bss_conf timestamp to last_tsfJohannes Berg
This value is not really very useful by itself, yet some drivers (including iwlwifi until I can figure out what it should do) use it. At least rename it to "last_tsf" to indicate the meaning and add a note that it may be really old. I suspect the value may become useful combined with the rx_status->mactime, but we don't (yet) store that value and pass it to the driver.

2012-03-12iwl3945: fix possible il->txq NULL pointer dereference in delayed worksStanislaw Gruszka
On il3945_down procedure we free tx queue data and nullify il->txq pointer. After that we drop mutex and then cancel delayed works. There is possibility, that after drooping mutex and before the cancel, some delayed work will start and crash while trying to send commands to the device. For example, here is reported crash in il3945_bg_reg_txpower_periodic(): https://bugzilla.kernel.org/show_bug.cgi?id=42766#c10 Patch fix problem by adding il->txq check on works that send commands, hence utilize tx queue.

2012-02-29iwlegacy: remove unused enum il4965_calib_enabled_stateGreg Dietsche
Remove the enum il4965_calib_enabled_state because it is not used. Signed-off-by: Greg Dietsche <Gregory.Dietsche@cuw.edu> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-29iwlegacy: remove enum iw_calib and related codeGreg Dietsche
Remove the enum il_calib. It defined one identifier: IL_CALIB_MAX. Remove the function il4965_calib_free_results. It was doing nothing because IL_CALIB_MAX is zero. Next, remove calib_results from the il_priv structure and also remove the associated return type/struct il_calib_result. Signed-off-by: Greg Dietsche <Gregory.Dietsche@cuw.edu> Signed-off-by: John W.

2012-02-29iwlegacy: Kconfig: Change Debug Option to be more clearGreg Dietsche

2012-02-29mac80211: handle non-bufferable MMPDUs correctlyJohannes Berg
This renames the IEEE80211_TX_CTL_POLL_RESPONSE TX flag to IEEE80211_TX_CTL_NO_PS_BUFFER and also uses it for non-bufferable MMPDUs (all MMPDUs but deauth, disassoc and action frames.) Previously, mac80211 would let the MMPDU through but not set the flag so drivers supporting some hardware aids for avoiding the PS races would then reject the frame.

2012-02-22iwlegacy: use writeb,writel,readl directlyStanislaw Gruszka
That change will save us some CPU cycles at run time. Having port-based I/O seems to be not possible for PCIe devices. Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2012-02-22iwlegacy: cleanup/fix memory barriersStanislaw Gruszka
wmb(), rmb() are not needed when writel(), readl() are used as accessors for MMIO. We use them indirectly via iowrite32(), ioread32(). What is needed mmiowb(), for synchronizing writes coming from different CPUs on PCIe bridge (see in patch comments). This fortunately is not needed on x86, where mmiowb() is just defined as compiler barrier. As iwlegacy devices are most likely not used on anything other than x86, this is not so important fix.
