Kernel API to get wireless connection info

[Salil Wadnerkar]

Does anyone know which `ieee80211` commands I need to get the wireless
connection info like SSID name, type (WPA, etc), and signal strength?
`ieee80211_ioctl` (https://man.netbsd.org/NetBSD-9.0/ieee80211_ioctl.9)
looks promising, but I cannot find the IOCTL commands that will get the
required info.
