Even before the series, it was allowed to create multiple ports of this kind but they were handled inconsistently. This series uses logical switches with multiple localnet ports (LSMLP) to implement what is called "routed provider networks" in OpenStack. To elaborate, this allows to natively model a network that has multiple segments with implied L3 routing between the segments realized by the fabric. A user can operate such a network as a single entity instead of deciding on which segment to choose for their port bindings. The assumption in this implementation is that while a logical switch can have multiple localnet ports, each chassis has only one of corresponding physical networks mapped. Meaning, if the same LS has localnet ports for networks A, B, and C, then each chassis can either be mapped to A, B, or C, but not several of the networks. (Note this doesn't mean that a chassis can't be mapped to network D, as long as it doesn't have a corresponding localnet port in this same logical switch.) Known bugs: - test case validating broadcast behavior fails on slow machines because of other service traffic getting in the way. Working on it.

Thanks! Fixed, pushed a new series version (with a fix for the test case failure mentioned in the cover letter).
Eg. Change the below from static void build_dhcpv4_options_flows(struct ovn_port *op, struct hmap *lflows, struct lport_addresses *lsp_addrs, const char *json_key, bool is_external) TO static void build_dhcpv4_options_flows(struct ovn_port *op, struct lport_addresses *lsp_addrs, const char *json_key, bool is_external, struct hmap *lflows) Since 'lflows' is modified. I know that ovn-northd.c has many functions which don't follow this method, but we can do so for newer functions atleast :).
