* WiFi: fix ieee80211_media_change() callersBjoern A. Zeeb2020-09-071-30/+0
| | | | | | | | | | | | | | | | | | | | | 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.

* [otus] enable 802.11n for 2GHz and 5GHz.Adrian Chadd2020-06-031-145/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This flips on basic 11n for 2GHz/5GHz station operation. * It flips on HT20 and MCS rates; * It enables A-MPDU decap - the payload format is a bit different; * It does do some basic checks for HT40 but I haven't yet flipped on HT40 support; * It enables software A-MSDU transmit; I honestly don't want to make A-MPDU TX work and there are apparently issues with QoS and A-MPDU TX. So I totally am ignoring A-MPDU TX; * MCS rate transmit is fine. I haven't: * A-MPDU TX, as I said above; * made radiotap work fully; * HT40; * short-GI support; * lots of other stuff that honestly no-one is likely to use. But!

| | | | | | | | | | | | | | | | | | | | | | | - Alignment issues: * Add missing __packed attributes + padding across all drivers; in most places there was an assumption that padding will be always minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) - padding was just missing. * Add __aligned(8) attribute for all Rx radiotap headers since they can contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so just drop the attribute here. Refresh ieee80211_radiotap(9) man page accordingly. - Since net80211 automatically updates channel frequency / flags in ieee80211_radiotap_chan_change() drop duplicate setup for these fields in drivers.

* [net80211] convert all of the WME use over to a temporary copy of WME info.Adrian Chadd2018-01-021-1/+4
| | | | | | | | | | | | | | | | | | | | 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. A lot of per-phy things need to be converted to per-VAP before P2P, 11ac firmware, etc stuff shows up. Notes: svn path=/head/; revision=327479

* [net80211] extend the ieee80211_rx_stats struct to include more information.Adrian Chadd2016-10-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are a variety of more interesting RX statistics that we should keep track of but we don't. This is a starting point for adding more information. Specifically: * now the RX rate information and some of the packet status is passed up; * The 32 bit or 64 bit TSF is passed up; * the PHY mode is passed up; * the "I'm decap'ed AMSDU!" state is passed up; * number of RX chains is bumped to 4. This is all mostly a placeholder for getting the data into the RX status before we pass it up to net80211 - unfortunately we don't yet enforce that drivers provide it, nor do we pass the provided info back up the stack so anyone can use the data. We're going to need to use some of this data moving forward. Notably, now that some hardware can do AMSDU decap for us (the intel iwm driver can do it when we flip it on; the ath10k port I'm doing does it for us) then we need to pass it up through the stack so the duplicate RX sequence numbers and crypto/IV details don't cause the packet to be dropped and/or counted against a replay counter. It's also the beginning of being able to do more interesting node accounting in net80211. Specifically, once drivers start populating per-packet rate information, AMPDU information, timestamps, etc, we can start providing histograms of rate-versus-RSSI, account for receive time spent per node and other such interesting things. (Note: I'm also hoping to include ranging and RTT information for future chipset support; and it's likely going to include it in this kind of fashion.) Notes: svn path=/head/; revision=306837
* net80211: ieee80211_ratectl*: switch to reusable KPIAndriy Voskoboinyk2016-10-021-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace various void * / int argument combinations with common structures: - ieee80211_ratectl_tx_status for *_tx_complete(); - ieee80211_ratectl_tx_stats for *_tx_update(); While here, improve amrr_tx_update() for a bit: 1. In case, if receiver is not known (typical for Ralink USB drivers), refresh Tx rate for all nodes on the interface. 2. 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()). If arguments are not big enough, they are just discarded after the next call. Fix: move counting into *_tx_update() (now otus(4) will zero out all node counters after every tx_update() call) Tested with: - Intel 3945BG (wpi(4)), STA mode. - WUSB54GC (rum(4)), STA / HOSTAP mode. - RTL8188EU (urtwn(4)), STA mode.
