I'd suggest you to check out the FAQ here - https://docs.openvswitch.org/en/latest/faq/contributing/ ----- Q: How do I add support for a new OpenFlow action? A: Add your new action to enum ofp_raw_action_type in lib/ofp-actions.c, following the existing pattern. Then recompile and fix all of the new warnings, implementing new functionality for the new action as needed. (If you configure with --enable-Werror, as described in the Open vSwitch on Linux, FreeBSD and NetBSD, then it is impossible to miss any warnings.) If you need to add an OpenFlow vendor extension action for a vendor that doesn’t yet have any extension actions, then you will also need to add the vendor to vendor_map in build-aux/extract-ofp-actions. Also, you will need to add support for the vendor to ofpact_decode_raw() and ofpact_put_raw() in lib/ofp-actions.c. (If you have a choice of how to design your vendor extension actions, it will be easier if you make them resemble the ONF and OVS extension actions.) ---- Also if you're interested you can check this out - https://dpdksummitbangalore2019.sched.com/event/LUEj/adding-a-new-ovs-action-numan-siddique-red-hat https://www.youtube.com/watch?v=6uKnpha15xY Thanks Numan > > > > > > > > > _______________________________________________ > discuss mailing list > disc...@openvswitch.org > https://mail.openvswitch.org/mailman/listinfo/ovs-discuss _______________________________________________ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
