*Number of discardable event buffers*

Type: ``int``

Help
====

Number of buffers in a separate buffer pool for events which
the HCI driver considers discardable. Examples of such events
could be e.g. Advertising Reports. The benefit of having such
a pool means that the if there is a heavy inflow of such events
it will not cause the allocation for other critical events to
block and may even eliminate deadlocks in some cases.
