wifi: mac80211: move interface config to new struct

2022-06-20T10:55:03Z

We'll use bss_conf for per-link configuration later, so move out all the non-link-specific data out into a new struct ieee80211_vif_cfg used in the vif. Some adjustments were done with the following spatch: @@ expression sdata; struct ieee80211_vif *vifp; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ ( -sdata->vif.bss_conf.var +sdata->vif.cfg.var | -vifp->bss_conf.var +vifp->cfg.var ) @bss_conf@ struct ieee80211_bss_conf *bss_conf; identifier var = { assoc, ibss_joined, aid, arp_addr_list, arp_addr_cnt, ssid, ssid_len, s1g, ibss_creator }; @@ -bss_conf->var +vif_cfg->var (though more manual fixups were needed, e.g. replacing "vif_cfg->" by "vif->cfg." in many files.)

mt7601u: check the status of device in calibration

2021-01-14T17:30:39Z

When the usb device being plugged out, before ieee80211 gets to know the hw being removed, it gets to know that the association status changed, and thus ask for the device to do the calibration. This causes error as the hw is absent. This can be avoid by checking the status of the device before sending the calibration request to the device.

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

mt7601u: remove warning when avg_rssi is zero

It turned out that we can run calibration without already received frames with RSSI data. In such case just don't update AGC register and don't print the warning.

mt7601u: use EWMA to calculate avg_rssi

2018-04-24T17:33:02Z

avr_rssi is not calculated correctly as we do not divide result by 256 (mt76 sum avg_rssi1 and avg_rssi2 and divide by 512). However dividing by 256 will make avg_rssi almost the same as last rssi value - not really an average. So use EWMA to calculate avg_rssi. I've chosen weight_rcp=4 to convergence quicker on signal strength changes. Signed-off-by: Stanislaw Gruszka Acked-by: Jakub Kicinski Signed-off-by: Kalle Valo
