107 Pre-emption of Active Event
133 - Event handle (0, 1) < Event preparation (2, 3) < Event/Rx done (4) < Tx
136 - LLL is vendor ISR, ULL is Mayfly ISR concept, Host is kernel thread.
147 - HCI/LLCP API

216 - New remote procedure handling
218 …* Note - for any given connection, there can only ever be ONE remote procedure in the remote proce…
220 - Miscellaneous minors
221 * pause/resume concepts - there are two (see spec for details)
224 * RX node retention - ensures no waiting for allocation of RX node when needed for notification
230 - Individual ZTEST unit test for each procedure
233 - Rx node handling is mocked
237 - Emulated versions of rx_demux/prepare context used in unit tests - testing ONLY procedure PDU flow
256 ----------
277 * Mayfly are multi-instance scalable ISR execution contexts
282 * Race-to-idle execution
283 * Lock-less, bare metal
