| * | wlcore: fix sparse warnings related to static functionsArik Nemtsov2012-06-05
| | | | | | | | | | | | | | | | | | | | | The "static" modifier was mistakenly forgotten for some functions. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
| * | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | With 4 pages (16Kb), we can't fit 10 frames in the aggregation buffer during iperf. This is the optimal for the firmware.

| * | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use hardcoded values for the different board types.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | In some cases it may be useful to force narrow-band SISO channels.

| * | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When allocating the fw_status structure, the space for the lower-driver private area was missing.
