Applying the filter flags directly as done since
commit 3474ad635d
Author: Johannes Berg <johannes.berg@intel.com>

iwlwifi: apply filter flags directly
broke 3945 under some unknown circumstances, as
reported by Alex.
Since I want to keep the direct application of
filter flags on iwlagn, duplicate the code into
both 3945 and agn and remove committing the
RXON that broke things from the 3945 version.

* struct iwl_cfg
|
|
* @fw_name_pre: Firmware filename prefix. The api version and extension
|
|
* (.ucode) will be added to filename before loading from disk. The
|
|
* filename is constructed as fw_name_pre<api>.ucode.
|
|
* @ucode_api_max: Highest version of uCode API supported by driver.
|
|
* @ucode_api_min: Lowest version of uCode API supported by driver.
|
|
* @pa_type: used by 6000 series only to identify the type of Power Amplifier
|
|
* @max_ll_items: max number of OTP blocks
|
|
* @shadow_ram_support: shadow support for OTP memory
|
|
* @led_compensation: compensate on the led on/off time per HW according
|
|
* to the deviation to achieve the desired led frequency.
|
|
* The detail algorithm is described in iwl-led.c
|
|
* @use_rts_for_aggregation: use rts/cts protection for HT traffic
|
|
* @chain_noise_num_beacons: number of beacons used to compute chain noise
|
|
* @adv_thermal_throttle: support advance thermal throttle
|
|
* @support_ct_kill_exit: support ct kill exit condition
|
|
* @support_wimax_coexist: support wimax/wifi co-exist
|
|
* @plcp_delta_threshold: plcp error rate threshold used to trigger
|
|
* radio tuning when there is a high receiving plcp error rate
|
|
* @chain_noise_scale: default chain noise scale used for gain computation
|
|
* @monitor_recover_period: default timer used to check stuck queues
|
|
* @temperature_kelvin: temperature report by uCode in kelvin
|
|
* @max_event_log_size: size of event log buffer size for ucode event logging
|
|
* @tx_power_by_driver: tx power calibration performed by driver
|
|
* instead of uCode
|
|
* @ucode_tracing: support ucode continuous tracing
|
|
* @sensitivity_calib_by_driver: driver has the capability to perform
|
|
* sensitivity calibration operation
|
|
* @chain_noise_calib_by_driver: driver has the capability to perform
|
|
* chain noise calibration operation
|
|
* @scan_antennas: available antenna for scan operation
|
|
*
|
|
* We enable the driver to be backward compatible wrt API version. The
|
|
* driver specifies which APIs it supports (with @ucode_api_max being the
|
|
* highest and @ucode_api_min the lowest). Firmware will only be loaded if
|
|
* it has a supported API version. The firmware's API version will be
|
|
* stored in @iwl_priv, enabling the driver to make runtime changes based
|
|
* on firmware version used.
|
|
*
|
|
* For example,
|
|
* if (IWL_UCODE_API(priv->ucode_ver) >= 2) {
|
|
* Driver interacts with Firmware API version >= 2.
|
|
* } else {
|
|
* Driver interacts with Firmware API version 1.
|
|
* }
|
|
*
|
|
* The ideal usage of this infrastructure is to treat a new ucode API
|
|
* release as a new hardware revision. That is, through utilizing the
|
|
* iwl_hcmd_utils_ops etc. we accommodate different command structures
|
|
* and flows between hardware versions (4965/5000) as well as their API
|
|
* versions.
