It bridges 29d70e9693SJohannes Berg * userspace and drivers, and offers some utility functionality associated 30d70e9693SJohannes Berg * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used 31d70e9693SJohannes Berg * by all modern wireless drivers in Linux, so that they offer a consistent 32d70e9693SJohannes Berg * API through nl80211. For backward compatibility, cfg80211 also offers 33d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely. 34d70e9693SJohannes Berg * 35d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum 36d70e9693SJohannes Berg * use restrictions. 37d70e9693SJohannes Berg */ 38d70e9693SJohannes Berg 39d70e9693SJohannes Berg 40d70e9693SJohannes Berg /** 41d70e9693SJohannes Berg * DOC: Device registration 42d70e9693SJohannes Berg * 43d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device 44d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs 45d70e9693SJohannes Berg * described below. 46d70e9693SJohannes Berg * 47d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 48d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 49d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 50d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 51d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 52d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 53d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 54d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 55d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 56d70e9693SJohannes Berg * 57d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 58d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 59d70e9693SJohannes Berg * structures here describe these capabilities in detail. 60d70e9693SJohannes Berg */ 61d70e9693SJohannes Berg 629f5e8f6eSJohannes Berg struct wiphy; 639f5e8f6eSJohannes Berg 64704232c2SJohannes Berg /* 65d3236553SJohannes Berg * wireless hardware capability structures 66d3236553SJohannes Berg */ 67d3236553SJohannes Berg 68d3236553SJohannes Berg /** 69d3236553SJohannes Berg * enum ieee80211_channel_flags - channel flags 70d3236553SJohannes Berg * 71d3236553SJohannes Berg * Channel flags set by the regulatory control code. 72d3236553SJohannes Berg * 73d3236553SJohannes Berg * @IEEE80211_CHAN_DISABLED: This channel is disabled. 748fe02e16SLuis R.
