------------------------------------------
Summary: Improved mbuf usage by the controller
Key: MYNEWT-100
URL: https://issues.apache.org/jira/browse/MYNEWT-100
Project: Mynewt
Issue Type: Improvement
Components: Nimble
Affects Versions: v0_8_0_beta1
Reporter: William San Filippo
Assignee: William San Filippo
Fix For: v0_9_0_rel
The current controller code can be improved by modifying how it uses mbufs.
Currently, the code grabs an mbuf for advertising and scanning and never
releases it. Furthermore, the controller uses an empty pdu per connection (it
is in the connection state machine structure) and also allocates mbufs (from
the msys pool) for LL control procedures. It would be better if the controller
either had its own smaller pool of mbufs or simply had one mbuf allocated per
connection as there will only be one control pdu or empty pdu outstanding at
any given time (per connection).
