Description (partial)

BFD neighbor goes down when applying ACL to interface towards neighbor.

ACL permits traffic according to logs, but BFD neighbor is torn down

- BFD running in echo mode
- ACL applied to interface towards neighbor

From DE local repro, issue seen only when 'log' option is added to the ACL. This will add latency to the keepalive packets due to logging them.
