* wlcore: remove duplicate BUG_ON during recoveryArik Nemtsov2012-06-05
| | | | | | | | | This BUG_ON also ignored the INTENDED_FW_RECOVERY flag. This would result in a BUG() when using the bug_on_recovery module parameter during multi-role. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

* wlcore: fix the CONF_TX_AC_ANY_TID to be 0xffYoni Divinsky2012-06-05

* wl12xx: set the irq polarity before loading the fwYoni Divinsky2012-06-05
| | | | | | | | | | The polarity should be set before the firmware is loaded since the firmware touches the same register. Access of the firmware and driver to the same register will cause a collision since there is no exclusion scheme.

* wlcore: use psd_type indexing according to specYoni Divinsky2012-06-05
| | | | | | | | | | | | | In ieee80211.h the uapsd bit mask is defined such that VO=BIT(0), VI=BIT(1), BK=BIT(2), BE=BIT(3). The firmware uses the indexing as defined in the ieee80211 spec, meaning that VO=3, VI=2, BK=1, BE=0. In AP mode when adding peer wlcore needs to convert the indexing accordingly.

* wlcore: fixes for connection_loss_workArik Nemtsov2012-06-05
| | | | | | | | | | | | | | We can't use cancel_delayed_work_sync() from functions that take the wl->mutex, since connection_loss_work also takes the mutex. This might result in a deadlock. Restructure the code so the work is synchronously canceled before taking the mutex. Avoid a bug where we would indefinitely delay the connection loss indication by re-queuing the connection loss work on consecutive beacon loss events.

* wlcore/wl12xx/wl18xx: don't use TX align quirk for wl127xLuciano Coelho2012-06-05
| | | | | | | | | | | | | | | Commit 4afc37 (wlcore: reorder identify_chip and get_hw_info) broke support for wl127x chips. When we moved the identify_chip operation to an earlier stage (ie. to the probe function), we broke wl127x support because during HW init we would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN. To avoid this, set this quirk in the identify_chip operations and only force it to be unset if the bus module doesn't support it. We were doing the opposite and setting the flag if the bus module supports it. Signed-off-by: Luciano Coelho <coelho@ti.com>
* wl18xx: change default tcp_checksum to falseAssaf Azulay2012-06-05
| | | | | | | | | | | as tcp check sum is going to be removed from firmware, and as there is a problem with getting dns in security when checksum is enabled, it was decided to disable it by default. for none security modes it can be enabled by module paramenter.

* wlcore: increase aggregation buffer size by one pageLuciano Coelho2012-06-05
| | | | | | | | | With 4 pages (16Kb), we can't fit 10 frames in the aggregation buffer during iperf. This is the optimal for the firmware. Thus, increase the buffer size by one page. Signed-off-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Arik Nemtsov <arik@wizery.com>
* wlcore/wl12xx/wl18xx: move lower driver debugfs to a subdirLuciano Coelho2012-06-05
| | | | | | | | | | | Instead of adding more files from the lower drivers into the same directory in debugfs as wlcore, we now add a subdirectory for the lower driver. This makes things a bit easier, because we can quickly see where the debugfs entry is implemented and what is specific to the lower driver.

* wl18xx: export low/high band component values as module paramsLuciano Coelho2012-06-05

* wl18xx: add power limit reference value to mac_and_phy settingsLuciano Coelho2012-06-05
| | | | | | | | | | | | With more recent PHY firmware versions (>8.1.0.0.116), we need to use the correct value for the pwr_limit_reference_11_abg parameter when setting the mac_and_phy options. For now we use a hardcoded 0xc8 as the value. This will be moved to the configuration binary when it gets implemented.

* wlcore: use proper values for supported local ratesLuciano Coelho2012-06-05
| | | | | | | | | | | We were setting all the rates bits when starting the AP role. Instead of doing this, we should set only the rates we really support (eg. MIMO rates or wide-channel rates). This commit changes that so that we always use the default rates (basic rates + MCS0-7) and add the values returned by the ap_get_mimo_wide_rate_mask operation.

* wl18xx: don't use MIMO when ht_mode is set to wideLuciano Coelho2012-06-05
| | | | | | | | | | | If the wl18xx module is loaded with ht_mode=wide (the default), we shouldn't use MIMO rates when the channel type is not HT40. Fix this by checking the ht_mode before deciding which rates to used. Additionally, set the ht_mode parameter explicitly to "wide" as the default.

* wlcore: create private static_data area and add operation to parse itLuciano Coelho2012-06-05
| | | | | | | | | | The wl18xx firmware has more information in the static_data than wl12xx.

* wlcore: use all AP basic rates as defaultLuciano Coelho2012-06-05
| | | | | | | | | | Sometimes we get a BSS_CHANGED_BEACON_ENABLED event before the basic rates have been properly set.

* wlcore: update beacon and probe_resp templates when rates changeLuciano Coelho2012-06-05
| | | | | | | | | | | | When the data rates change, we get BSS_CHANGED_BASIC_RATES. At this point, we should update all the templates to match the new rates.

Unfortunately, the array that contains the actual descriptors is in the middle of the fw_status structure.
