For backward compatibility, cfg80211 also offers 34d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely. 35d70e9693SJohannes Berg * 36d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum 37d70e9693SJohannes Berg * use restrictions. 38d70e9693SJohannes Berg */ 39d70e9693SJohannes Berg 40d70e9693SJohannes Berg 41d70e9693SJohannes Berg /** 42d70e9693SJohannes Berg * DOC: Device registration 43d70e9693SJohannes Berg * 44d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device 45d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs 46d70e9693SJohannes Berg * described below. 47d70e9693SJohannes Berg * 48d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 49d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 50d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 51d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 52d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 53d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 54d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 55d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 56d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 57d70e9693SJohannes Berg * 58d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 59d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 60d70e9693SJohannes Berg * structures here describe these capabilities in detail. 61d70e9693SJohannes Berg */ 62d70e9693SJohannes Berg 639f5e8f6eSJohannes Berg struct wiphy; 649f5e8f6eSJohannes Berg 65704232c2SJohannes Berg /* 66d3236553SJohannes Berg * wireless hardware capability structures 67d3236553SJohannes Berg */ 68d3236553SJohannes Berg 69d3236553SJohannes Berg /** 70d3236553SJohannes Berg * enum ieee80211_channel_flags - channel flags 71d3236553SJohannes Berg * 72d3236553SJohannes Berg * Channel flags set by the regulatory control code. 73d3236553SJohannes Berg * 74d3236553SJohannes Berg * @IEEE80211_CHAN_DISABLED: This channel is disabled. 758fe02e16SLuis R.
