2010-01-12iwlwifi: add IEEE80211_AMPDU_TX_OPERATIONALWey-Yi Guy
mac80211 do not check the return code now, what if mac80211 does start using the return code? IEEE80211_AMPDU_TX_OPERATIONAL is a valid action, just iwlwifi driver do not need to take any action for it; so instead of return "-EINVAL", it is a good program practice to return "-EOPNOTSUPP" to make sure mac80211 will not get wrong impression.

2010-01-12mwl8k: move receive processing to taskletLennert Buytenhek
Like how TX reclaim is done in a tasklet, move receive processing to tasklet context as well. This can have nice benefits for CPU utilisation and throughput, especially at 3-stream rates. (Use the same CLEAR_SEL trick as the TX reclaim tasklet does, to avoid having to touch the interrupt mask registers.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

2010-01-12mwl8k: keep TX_DONE interrupt masked while transmit reclaim is runningLennert Buytenhek
By making use of the CLEAR_SEL feature of the mwl8k host interface interrupt controller, we can keep the TX_DONE interrupt source masked while the transmit reclaim tasklet is running (NAPI style) without having to touch the interrupt controller's interrupt mask register when entering or exiting polling mode, and without having to do any more register reads/writes than we do now. When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading the interrupt status register will clear the TX_DONE status bit if it was set, allowing it to be set again if a new TX_DONE event arrives while we are running the TX reclaim tasklet, but such a new event will then not trigger another PCI interrupt until a zero is written to the TX_DONE interrupt status register bit. I.e., if we write a zero to the TX_DONE interrupt source bit in the interrupt status register when the TX reclaim tasklet thinks it's done, a PCI interrupt will be triggered if a new TX_DONE event arrived from the hardware between us deciding that there is no more work to do and re-enabling the TX_DONE interrupt source, thereby avoiding the classic NAPI poll mode exit race that would otherwise occur.

2010-01-12mwl8k: allow limiting the amount of transmit reclaim doneLennert Buytenhek

2010-01-12mwl8k: implement AP firmware station database maintenanceLennert Buytenhek
STA firmware uses UPDATE_STADB to manipulate the hardware station database, whereas AP firmware uses SET_NEW_STN -- this implements the latter, and hooks it into mwl8k_sta_notify(), to be used if we're running on AP firmware.

2010-01-12mwl8k: add the AP version of USE_FIXED_RATELennert Buytenhek
As with the STA version, unicast will use auto rate adaptation, but the AP version allows setting the rates to be used for management and multicast transmissions, which can be set based on the BSS basic rate set.

2010-01-12mwl8k: simplify mwl8k_cmd_use_fixed_rate()Lennert Buytenhek

2010-01-12mwl8k: bump the transmit wait timeout to 5 secondsLennert Buytenhek
While it is reasonable to expect that at least one transmit ring entry will be processed per second while we are waiting for the transmit rings to drain, the firmware can end up doing batching of transmit ring status writeback, which means that the transmit rings can appear stuck for more than a second at a time. Bump the TX drain wait timeout up from 1 to 5 seconds to account for this. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
2010-01-12mwl8k: undo transmit queue 0/1 swapping in mwl8k_cmd_set_edca_params()Lennert Buytenhek
The comment and code in mwl8k_cmd_set_edca_params() suggest that the mapping between SET_EDCA_PARAMS queue numbers and transmit rings isn't actually 1:1, while tests show that the mapping is in fact 1:1. So, get rid of the transmit queue 0/1 swapping. Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-01-12ath5k: Implement mac80211 callback set_coverage_classLukáš Turek
The callback sets slot time as specified in IEEE 802.11-2007 section 17.3.8.6 (for 20MHz channels only for now) and raises ACK and CTS timeouts accordingly.

2010-01-12ath5k: Reimplement clock rate to usec conversionLukáš Turek
The original code was correct in 802.11a mode only, 802.11b/g uses different clock rates. The new code uses values taken from FreeBSD HAL and should be correct for all modes including turbo modes. The former rate calculation was used by slope coefficient calculation function ath5k_hw_write_ofdm_timings. However, this function requires the 802.11a values even in 802.11g mode. Thus the use of ath5k_hw_htoclock was replaced by hardcoded values. Possibly the slope coefficient calculation is not related to clock rate at all.

2010-01-12ath5k: Fix functions for getting/setting slot timeLukáš Turek
Functions ath5k_hw_get_slot_time and ath5k_hw_set_slot_time were converting microseconds to clocks only for AR5210, although it's needed for all supported devices. The conversion was moved outside the hardware-specific branches. The original code also limited minimum slot time to 9, while turbo modes use 6, this was fixed too.

2010-01-12ath9k: re-enable ps by default for new single chip familiesLuis R. Rodriguez
The newer single chip hardware family of chipsets have not been experiencing issues with power saving set by default with recent fixes merged (even into stable). The remaining issues are only reported with AR5416 and since enabling PS by default can increase power savings considerably best to take advantage of that feature as this has been tested properly. For more details on this issue see the bug report: http://bugzilla.kernel.org/show_bug.cgi?id=14267 We leave AR5416 with PS disabled by default, that seems to require some more work.
