* nl80211: restore iterating over all devices in nl80211_phy2ifname()Andre Heider2023-02-061-4/+6
| | | | | | | | | | | | | | | This reverts to the earlier behaviour, because: * phys can be renamed, which breaks hardcoding "phy%d" * /sys/class/ieee80211/*/device can return networks of other phys, since "device" is a symlink which can have multiple phys The earlier behaviour fixes both points.

* nl80211: prefer non-supplicant-based devicesAndre Heider2023-01-201-4/+12
| | | | | | | | | | | | | If a phy has multiple devices, prefer non-supplicant-based ones as per link_mode, see [0] and [1]. The nl80211 API provides more information than wpa_supplicant/hostapd does, like HT/VHT operation, which are used by e.g. luci's channel analysis.

* nl80211: simplify iterating over phy's devicesAndre Heider2023-01-201-12/+9
| | | | | | | There's no need to iterate over all devices in /sys/class/net and check if the phy index matches, sysfs already provides per phy devices. Signed-off-by: Andre Heider <a.heider@gmail.com>

* nl80211: add "mhz" and "band" to iwinfo_scanlist_entryAndre Heider2023-01-201-3/+22
| | | | | | | | | Providing the channel alone isn't clear as there're overlapping channels on e.g. band 2 and 6. Note: This changes the ABI. Signed-off-by: Andre Heider <a.heider@gmail.com>
* nl80211: add "band" to iwinfo_freqlist_entryAndre Heider2023-01-201-0/+1
| | | | | | | | | So that consumers don't have to fiddle around with mapping frequencies to bands, which everyone seems to do a little differently. Note: This changes the ABI. Signed-off-by: Andre Heider <a.heider@gmail.com>

* devices: add support for declaring compatible matched devicesJo-Philipp Wich2023-01-101-63/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | Some device have embedded wifi card that are not connected with usb or internall with pci. Such device have fake device_id and only the vendor_id actually reflect something real but internally they don't have any id and are just matched by the node compatible binding in DT. We currently match this with a big if-else to match the single devices but this can be improved and be matched directly in devices.txt Rework this so that we can drop the big if-else and move the matching to devices.txt When a device is matched using compatible in iwinfo the hardware will be flagged as embedded and won't print empty ids. Update devices.txt by migrating all the compatible matching device from fake id to compatible matching.

| | | | | | | | | | | | | | | | | | | | | | | It's too slow to do it all over again and again, especially with e.g. luci constantly polling. Before: $ time iwinfo phy0 info real 0m 0.54s $ time iwinfo radio0 info real 0m 0.70s $ time ubus call luci-rpc getWirelessDevices real 0m 0.67s After: $ time iwinfo phy0 info real 0m 0.04s $ time iwinfo radio0 info real 0m 0.09s $ time ubus call luci-rpc getWirelessDevices real 0m 0.17s Signed-off-by: Andre Heider <a.heider@gmail.com>
* nl80211: add ability to describe USB devicesJo-Philipp Wich2022-12-151-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | Treat USB vendor and product IDs like PCI subsystem vendor and device IDs respectively to allow describing USB devices as `0000 0000 $vid $pid` in the hardware database. As a side effect, this also skips potentially expensive MTD lookups on embedded devices with plugged in USB radios. With a 5.15 kernel, such MTD lookups even spam dmesg with: mtdblock: MTD device 'factory' is NAND, please consider using UBI block devices instead.

* iwinfo: nl80211: fix hwmode parsing for multi-band NICsDavid Bauer2022-04-231-6/+28
| | | | | | | | | | | | | | In case a NIC supports multiple frequency bands, the supported hw-modelist might not contain all valid hwmodes, as B/G/AD hwmodes are only included based on the last parsed supported frequency. In case a radio supports multiple bands, this might result in these hwmodes not being flagged as supported. Circumvent this by tracking all seen frequency bands using a bitmask which later determined which HW modes are listed as supported. Signed-off-by: David Bauer <mail@david-bauer.net>

* iwinfo: detect QCA IPQ4019 WiSoC from FDTDaniel Golle2021-01-051-0/+30
| | | | | | | | | | | As it's the most reliable and straight forward way on modern platforms, detect the hardware ID by checking the 'compatible'-string of non-PCI (ie. built-in) devices. As this is only relevant for WiSoCs, there won't be that many records, so it's not worth making any larger structural changes. Hence just match the compatible string and translate it into fake PCI IDs. Signed-off-by: Daniel Golle <daniel@makrotopia.org>
