The structure hif_req_join come from hardware API. It is not intended to be manipulated in upper layers of the driver. In add, current code for hif_join() is too dumb. It should pack data with hardware representation instead of leaving all work to the caller. Signed-off-by:

hif_update_ie() is only called to change the beacon template. So, specialize this function and simplify the way to call it. Signed-off-by:

SSID is hidden in beacon but firmware has to know to which probe requests it has to answer. Signed-off-by:

wfx_bss_info_changed() is not called from atomic contexts. So, it is not necessary to raise an asynchronous work to change ERP. Thus wfx_set_cts_work() become useless. Signed-off-by:

setbssparams_done was here to ensure that the firmware does not enable powersave before to get the first beacon. However, mac80211 already ensures it gets a beacon before to associate to the BSS. And even, if it won't, the firmware wake up at least on every DTIM, which is sufficient to finalize the association. Signed-off-by:

Current code keeps a copy of bss_conf->cqm_rssi_thold in wfx_vif. There is no sane reason for that. Signed-off-by:

It seems that current code try to save calls to hif_beacon_transmit() by keeping a copy of the previous value of bss_conf->enable_beacon. However, hif_beacon_transmit() does not cost so much and mac80211 already take care to not send useless events. Signed-off-by:

It is not necessary to keep a copy of dtim_period in wfx_vif. Prefer to just rely on bss_conf->dtim_period. Signed-off-by:
-
Jérôme Pouiller authored
Current code parse the TIM and retrieve the DTIM period. It is far easier to rely on bss_info_changed() for this job. It is no more necessary to run task asynchronously. So set_beacon_wakeup_period_work is now useless. Signed-off-by:

Current code of wfx_flush() force to drop packets in some contexts. However, there is no obvious reasons to do that. It looks like a workaround for a bug with the old implementation of __wfx_flush(). Signed-off-by:
-
Jérôme Pouiller authored
wfx_tx_queues_clear() only clear not yet sent requests. So, it always necessary to wait for tx_queue_stats.wait_link_id_empty whatever the value of "drop" argument. In add, it is not necessary to return with tx queue locked since all calls to __wfx_flush() unlock the tx queue just after the call to __wfx_tx_flush(). Signed-off-by:

This function built probe response from data retrieved in beacon. Yet, this job can be done with ieee80211_proberesp_get(). So, we can simplify that code (and fix bugs like inclusion of TIM in probe responses). Signed-off-by:
-
Jérôme Pouiller authored
In fact, wfx_upload_beacon() uploads beacon and probe response. So, rename it in wfx_upload_ap_templates(). The call to wfx_fwd_probe_req() has nothing to do with template uploading, so relocate it. Signed-off-by:

Now that wfx_config() only handles IEEE80211_CONF_CHANGE_PS, it can be simplified. Signed-off-by:

mac80211 and the device are both able to control tx power per vif. But, the current code retrieve tx power from wfx_config(). So, it does not allow to setup the tx power independently for each vif. Driver just has to rely on bss_conf->txpower to get the correct information. In add, it is no more necessary to protect access to wdev->output_power with scan_lock. Signed-off-by:

wvif->ht_info contains useless copies of sta->ht_cap and bss_conf->ht_operation_mode. Prefer to retrieve information from the original structs instead of rely on wvif->ht_info. Signed-off-by:

wvif->ht_info.ht_cap is a useless copy of sta->ht_cap. It makes no sense to rely on it. Signed-off-by:

Most of the commands that are sent to device should take struct in argument. In the current code, when this struct is binary compatible with a __le32, the driver use a __le32. This behavior is error prone. This patch fixes that and uses the specialized structs instead. Signed-off-by:

The structure hif_mib_arp_ip_addr_table come from hardware API. It is not intended to be manipulated in upper layers of the driver. In add, current code for hif_set_arp_ipv4_filter() is too dumb.

Hardware API use 10th of dBm for output power unit. Upper layers should use same units than mac80211 and the conversion should be done by low level layer of the driver (hif_set_output_power()) In add, current code of hif_set_output_power() use a __le32 while the device API specify a specific structure for this.

The structure hif_mib_set_tx_rate_retry_policy come from hardware API. It is not intended to be manipulated in upper layers of the driver. So, this patch relocate handling of this structure to hif_set_tx_rate_retry_policy() (the low level function). Signed-off-by:
-
Jérôme Pouiller authored
Rate policies (aka. tx_rate_retry_policy in hardware API) are sent to device asynchronously from tx requests. So, the device maintains a list of active rate policies and the tx requests only reference an existent rate policy. The device API allows to send multiple rate policies at once. However, this property is very rarely used. We prefer to send rate policies one by one and simplify the architecture. Signed-off-by:

It appears that commit 8c7128c4 ("staging: align to fix warnings of line over 80 characters") do slightly more than what is explained in commit log. Especially, it changes the output of the file rx_stats from debugfs. From some point of view, this file can be considered as a part of the API. Any change on it should be clearly announced. Since the change introduced does not seems to have any justification, revert it. Reported-by:

Checkpatch reports 'WARNING: printk() should include KERN_<LEVEL> facility level'. Fix this by specifying a relevant KERN_<LEVEL> value for each line in which it was missing. Once they are fixed, checkpatch reports 'WARNING: Prefer [subsystem eg: netdev]_dbg([subsystem]dev, ... then dev_dbg(dev, ... then pr_debug(... to printk(KERN_DEBUG ...'. Fix this by replacing relevant printk_<level> statements with their netdev_<level> equivalent. Signed-off-by:
