It bridges 32d70e9693SJohannes Berg * userspace and drivers, and offers some utility functionality associated 33d70e9693SJohannes Berg * with 802.11. cfg80211 must, directly or indirectly via mac80211, be used 34d70e9693SJohannes Berg * by all modern wireless drivers in Linux, so that they offer a consistent 35d70e9693SJohannes Berg * API through nl80211. For backward compatibility, cfg80211 also offers 36d70e9693SJohannes Berg * wireless extensions to userspace, but hides them from drivers completely. 37d70e9693SJohannes Berg * 38d70e9693SJohannes Berg * Additionally, cfg80211 contains code to help enforce regulatory spectrum 39d70e9693SJohannes Berg * use restrictions. 40d70e9693SJohannes Berg */ 41d70e9693SJohannes Berg 42d70e9693SJohannes Berg 43d70e9693SJohannes Berg /** 44d70e9693SJohannes Berg * DOC: Device registration 45d70e9693SJohannes Berg * 46d70e9693SJohannes Berg * In order for a driver to use cfg80211, it must register the hardware device 47d70e9693SJohannes Berg * with cfg80211. This happens through a number of hardware capability structs 48d70e9693SJohannes Berg * described below. 49d70e9693SJohannes Berg * 50d70e9693SJohannes Berg * The fundamental structure for each device is the 'wiphy', of which each 51d70e9693SJohannes Berg * instance describes a physical wireless device connected to the system. Each 52d70e9693SJohannes Berg * such wiphy can have zero, one, or many virtual interfaces associated with 53d70e9693SJohannes Berg * it, which need to be identified as such by pointing the network interface's 54d70e9693SJohannes Berg * @ieee80211_ptr pointer to a &struct wireless_dev which further describes 55d70e9693SJohannes Berg * the wireless part of the interface, normally this struct is embedded in the 56d70e9693SJohannes Berg * network interface's private data area. Drivers can optionally allow creating 57d70e9693SJohannes Berg * or destroying virtual interfaces on the fly, but without at least one or the 58d70e9693SJohannes Berg * ability to create some the wireless device isn't useful. 59d70e9693SJohannes Berg * 60d70e9693SJohannes Berg * Each wiphy structure contains device capability information, and also has 61d70e9693SJohannes Berg * a pointer to the various operations the driver offers. The definitions and 62d70e9693SJohannes Berg * structures here describe these capabilities in detail. 63d70e9693SJohannes Berg */ 64d70e9693SJohannes Berg 659f5e8f6eSJohannes Berg struct wiphy; 669f5e8f6eSJohannes Berg 67704232c2SJohannes Berg /* 68d3236553SJohannes Berg * wireless hardware capability structures 69d3236553SJohannes Berg */ 70d3236553SJohannes Berg 71d3236553SJohannes Berg /** 72d3236553SJohannes Berg * enum ieee80211_channel_flags - channel flags 73d3236553SJohannes Berg * 74d3236553SJohannes Berg * Channel flags set by the regulatory control code. 75d3236553SJohannes Berg * 76d3236553SJohannes Berg * @IEEE80211_CHAN_DISABLED: This channel is disabled. 778fe02e16SLuis R.
