Current LiSA (release) version is defined in the main Makefile, by means of 3 macros: * MAJOR: changes when the whole engine/api is redesigned; * MINOR: changes when kernel <-> userspace api is modified (usually when new features are added); * PATCH: changes when things are fixed or for small functionality improvements.

Adding a menu entry for the CLI This document shows how to add a menu entry for the CLI. Usually the first thing anyone would want to do for their protocol implementation is to enable that protocol for some of the available interfaces. Thus, in describing the steps to follow, we'll consider adding an Enable option for the RSTP protocol.

Port states * mrouter (router port) * subscriber (port belongs to established multicast group) * none Forwarding cases (igmp snooping enabled on vlan) * multicast traffic received on “none” port * if no mrouter present, flood to all ports * otherwise flood to mrouter ports

Userspace protocol implementation This page describes the steps to follow in implementing basic message passing for an userspace protocol. As an actual example we'll use RSTP. Kernel modifications First of all, we have to define a dummy protocol type used in our custom protocol implementation. This has no meaning whatsoever with respect to the protocol fields of actual ethernet frames, it is only used in LiSA's internal logic. We include the type in net_switch.h:
