32 * DOC: Key handling basics
34 * Key handling in mac80211 is done based on per-interface (sub_if_data)
36 * each station key also belongs to that interface.
39 * that are implemented in software, for each key the hardware is asked
40 * to enable that key for offloading but if it cannot do that the key is
43 * There is currently no way of knowing whether a key is handled in SW
46 * All key management is internally protected by a mutex. Within all
47 * other parts of mac80211, key references are, just as STA structure
49 * unprotected, namely the key->sta dereferences within the hardware
51 * remove the key which waits for an RCU grace period.
82 * 1. SKB resize was skipped because no key was added but just before in increment_tailroom_need_count()
83 * the xmit key is added and SW encryption kicks off. in increment_tailroom_need_count()
86 * just before xmit one of the key is deleted and SW encryption kicks in increment_tailroom_need_count()
