* rtwn: narrow the epoch areaBjoern A. Zeeb2020-09-291-6/+12
| | | | | | | | | | | | | | | | | | Rather than placing the epoch around the entire receive loop which might call into rtwn_rx_frame() and USB and sleep, split the loop into two[1] and leave us with one unlock/lock cycle as well.

* net80211: enhance getflags*() and ieee80211_add_channel*()Bjoern A. Zeeb2020-08-241-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For ieee80211_add_channel+*() we are passing in an int flag for ht40 and in some cases another int flag for vht80 where we'd only need two bits really. Convert these variables to a bitflag and fold them together into one. This also allows for VHT160 and VHT80P80 and whatever may come to be considered. Define the various options currently needed. Change the drivers (rtwn and rsu) which actually set this bit to non-0. For convenience the "1" currently used for HT40 is preserved. Enahnce getflags_5ghz() to handle the full set of VHT flags based on the input flags from the the driver. Update the regdomain implementation as well to make use of the new flags and deal with higher [V]HT bandwidths. ieee80211_add_channel() specifically did not take flags so it will not support naything beyond 20Mhz channels. Note: I am not entirely happy with the "cbw_flag[s]" name, but we do use chan_flags elsewhere already.

* Fix ieee80211_radiotap(9) usage in wireless drivers:Andriy Voskoboinyk2019-03-112-5/+2
| | | | | | | | | | | | | | | | | | | | | | | - 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Fix data frames transmission via POWER_STATUS register setup - it seems to be set by MACID_CONFIG firmware command, which was broken* in r290439 and later disabled in r307529. We can re-enable it later if / when firmware rate adaptation will be ready; however, this step will be required anyway - for firmware-less builds. - Force RTS / CTS protection frame rate to CCK1 (this rate works fine without any additional setup; no better workaround is known yet). The problem was not observed on the channel 1 or with CCK1 rate enforced ('ifconfig wlan0 ucastrate 1' for 11 b/g; not possible for 11n networks due to ifconfig(8) bug). * I'm not sure if it works before r290439 because - AFAIR - I never seen firmware rate adaptation working for 10-STABLE urtwn(4) (It needs EN_BCN bit set and RSSI updates at least).

| | | | | | | | | | | | | | | | | | | | 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
