25 * The key cache is used for h/w cipher state and also for
26 * tracking station state such as the current tx antenna.
27 * We also setup a mapping table between key cache slot indices
28 * and station state to short-circuit node lookups on rx.
29 * Different parts have different size key caches. We handle
30 * up to ATH_KEYMAX entries (could dynamically allocate state).
