* [iwn] Flip over to use VAP flags rather than ic flags for thingsAdrian Chadd2021-03-261-14/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | net80211 changed a while back to support per-VAP config for things rather than it being global. This is to support firmware NICs that support per-VAP flags and configuration where the firmware will figure out how to combine them. However, it introduced a fun timing issue - those changes used to happen to the shared ic state before newstate() was called, but now they're also tasks and they can happen /after/. This isn't a problem for ath(4), but it exposed some interesting timing and config bugs here. Notably, I saw short slot NOT being configured in 5GHz mode during some associations, so 5GHz stuff would hang or behave poorly. Other times the follow-up auth has the right config, so it didn't hang. So for now, just flip this over to using the per-VAP flags which are correct when newstate() is called. net80211 should also have those flags synch'ed to the global ic state before newstate() runs and that can come in a subsequent commit. Whilst here also fix plcp to be consistently logged as a hex value. Tested: * iwn(4) Intel 6205, STA mode, both 2GHz and 5GHz Differential Revision: https://reviews.freebsd.org/D29379 Reviewed by: bz
* Provide MS() and SM() macros for 80211 and wireless drivers.Bjoern A. Zeeb2020-09-241-4/+2
| | | | | | | | | | | | | | | | | | | We have (two versions) of MS() and SM() macros which we use throughout the wireless code. Change all but three places (ath_hal, rtwn, and rsu) to the newly provided _IEEE80211_MASKSHIFT() and _IEEE80211_SHIFTMASK() macros. Also change one internal case using both _S and _M instead of just _S away from _M (one of the reasons rtwn and rsu were not changed). This was done semi-mechanically. No functional changes intended.

* WiFi: fix ieee80211_media_change() callersBjoern A. Zeeb2020-09-071-13/+2
| | | | | | | | | | | | | | | | | | | | | In r178354 with the introduction of multi-bss ("vap") support factoring out started and with r193340 ieee80211_media_change() no longer returned ENETRESET but only 0 or error. As ieee80211(9) tells the ieee80211_media_change() function should not be called directly but is registered with ieee80211_vap_attach() instead. Some drivers have not been fully converted. After fixing the return checking some of these functions were simply wrappers between ieee80211_vap_attach() and ieee80211_media_change(), so remove the extra function, where possible as well.

| | | | | | | | | | | | | | | | | | | | This removes the direct WME info access in the ieee80211com struct and instead provides a method of fetching the data. Right now it's a no-op but eventually it'll turn into a per-VAP method for drivers that support it (eg iwn, iwm, upcoming ath10k work) as things like p2p support require this kind of behaviour. Tested: * ath(4), STA and AP mode TODO: * yes, this is slightly stack size-y, but it is an important first step to get drivers migrated over to a sensible WME API.

There was a misuse: - otus(4) sends non-decreasing counters (as originally intended); - but ural(4), rum(4) and run(4) are using 'read & clear' registers to obtain statistics for some period of time (and those 'last period' values are used as arguments for tx_update()).
