* mac80211: remove hw.conf.channel usage where possibleMichal Kazior2012-04-13
| | | | | | | | | | | | | | Removes hw.conf.channel usage from the following functions: * ieee80211_mandatory_rates * ieee80211_sta_get_rates * ieee80211_frame_duration * ieee80211_rts_duration * ieee80211_ctstoself_duration This is in preparation for multi-channel operation.

* ath9k_hw: Remove BTCOEX initvalsSujith Manoharan2012-04-13
| | | | | | | | | | | | | | | | | The MAX_TXPWR table for BTCOEX is not needed for AR9462. Programming these values to the HW results in undesirable behavior - for example, large number of delimiter/data underruns are seen in AES-CCMP mode. Also, registers like AR_PCU_MISC_MODE2 return 0xdeadbeef after the BTCOEX_MAX power table is programmed to the HW, and frames being transmitted end up being looped back to the RX engine, an example being beacon frames in IBSS mode. Remove this table for now - this fixes CCMP performance and general IBSS usage. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* mac80211: fix an issue in ieee80211_tx_info count field managementLorenzo Bianconi2012-04-13
| | | | | | | | | | | | I noticed a possible issue in the status count field management of the ieee80211_tx_info data structure. In particular, when the AGGR processing is employed, status.rates[].count is set just for the first frame and not for others belonging to the same burst, leading to wrong statistic data in the mac80211 debug file system.

The call to wl1271_set_block_size() decides whether SDIO block size alignment can be used or not. In case we're using SPI, we can't use the block size alignment, so the function returns false. So we set the quirk when wl1271_set_block_size() returns true and let the wl12xx lower driver unset the bit for wl127x (since it doesn't support this quirk).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One chip family employs immediate Tx completion, where knowledge of completed packets is given as part of the FW status.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The only difference in the read_data operations is that some chips need to prepare the data to be read before reading. So instead of having a mandatory read_data operation, we now have an option prepare_data operation that only needs to be implemented for chips that require it. In the wl12xx lower driver, we only set the prepare_data operation for wl127x chips.
