The 23 bytes default is quite limiting. When SMP has been enabled we

second).

297f4f481f Bluetooth: Split HCI command & event buffers to two pools
The HCI commands and events have slightly different requirements
(e.g. max sizes, or the fact that events don't need any user data) so
it makes sense to keep them separate. The total count is kept at 8 (2
+ 6) but the ACL_OUT count is modified to not exceed the event count
(to avoid inability of handling bursts of Number of Completed Packets
events). The ACL_IN count is also modified to keep these symmetric for
now.

c1f007687f net: Add initial generic buffer implementation
We need to have a generic buffer API in order to efficiently transfer
data between different subsystems. The first such case will be the
Networking and Bluetooth subsystems where 6LoWPAN data will be passed
back and forth.

The needed API needs to provide enough flexibility for different
buffer sizes as well as custom protocol-specific context data.

The implementation offered in this patch follows the general design of
the existing Networking and Bluetooth buffer implementations by using
a backing array of buffer which is fed into a "free buffers" FIFO for
management. The main difference is that the API allows specifying
variable sized buffers for each created pool, as well as a minimum
amount of "user data" that's allocated as part of each buffer.

There's also an optional destroy callback that's e.g. useful for HCI
flow control in Bluetooth (for notifying the controller of available
buffers).
