wifi: mac80211: remove mesh forwarding congestion check

2023-02-14T11:25:23Z

Now that all drivers use iTXQ, it does not make sense to check to drop tx forwarding packets when the driver has stopped the queues. fq_codel will take care of dropping packets when the queues fill up Signed-off-by: Felix Fietkau Link: https://lore.kernel.org/r/20230213100855.34315-3-nbd@nbd.name Signed-off-by: Johannes Berg

wifi: mac80211: Drop support for TX push path

2022-10-10T09:06:14Z

All drivers are now using mac80211 internal queues (iTXQs). Drop mac80211 internal support for the old push path. Signed-off-by: Alexander Wetzel Signed-off-by: Johannes Berg

wifi: mac80211: implement link switching

2022-09-06T08:17:20Z

Implement an API function and debugfs file to switch active links. Also provide an async version of the API so drivers can call it in arbitrary contexts, e.g. while in the authorized callback. Signed-off-by: Johannes Berg

wifi: mac80211: RCU-ify link/link_conf pointers

2022-07-15T09:43:14Z

Since links can be added and removed dynamically, we need to somehow protect the sdata->link[] and vif->link_conf[] array pointers from disappearing when accessing them without locks. RCU-ify the pointers to achieve this, which requires quite a bit of rework. Signed-off-by: Johannes Berg

wifi: mac80211: switch airtime fairness back to deficit round-robin scheduling

2022-07-01T08:51:41Z

This reverts commits 6a789ba679d652587532cec2a0e0274fda172f3b and 2433647bc8d983a543e7d31b41ca2de1c7e2c198. The virtual time scheduler code has a number of issues: - queues slowed down by hardware/firmware powersave handling were not properly handled. - on ath10k in push-pull mode, tx queues that the driver tries to pull from were starved, causing excessive latency - delay between tx enqueue and reported airtime use were causing excessively bursty tx behavior The bursty behavior may also be present on the round-robin scheduler, but there it is much easier to fix without introducing additional regressions Signed-off-by: Felix Fietkau Acked-by: Toke Høiland-Jørgensen Link: https://lore.kernel.org/r/20220625212411.36675-1-nbd@nbd.name Signed-off-by: Johannes Berg

wifi: mac80211: make some SMPS code MLD-aware

2022-06-20T10:55:30Z

Start making some SMPS related code MLD-aware. This isn't really done yet, but again cuts down our 'deflink' reliance. Signed-off-by: Johannes Berg

wifi: mac80211: reorg some iface data structs for MLD

2022-06-20T10:55:06Z

Start reorganizing interface related data structures toward MLD. The most complex part here is for the keys, since we have to split the various kinds of GTKs off to the link but still need to use (for WEP) the other keys as a fallback even for multicast frames. Signed-off-by: Johannes Berg

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.)

mac80211: use ifmgd->bssid instead of ifmgd->associated->bssid

2022-05-16T07:13:22Z

Since we always track the BSSID there when we get associated, these are equivalent, but ifmgd->bssid saves a dereference and thus makes the code a bit smaller, and more readable. Signed-off-by: Johannes Berg

mac80211: remove unused macros

2022-02-04T15:26:27Z

Various macros in mac80211 aren't used, remove them. In one case it's used under ifdef, so ifdef it for the W=2 warning.
