charset=UTF-8 +Content-Transfer-Encoding: 8bit + +Implements an optional, per bridge port flag and feature to deliver +multicast packets to any host on the according port via unicast +individually. This is done by copying the packet per host and +changing the multicast destination MAC to a unicast one accordingly. + +multicast-to-unicast works on top of the multicast snooping feature of +the bridge. Which means unicast copies are only delivered to hosts which +are interested in it and signalized this via IGMP/MLD reports +previously. + +This feature is intended for interface types which have a more reliable +and/or efficient way to deliver unicast packets than broadcast ones +(e.g. wifi). + +However, it should only be enabled on interfaces where no IGMPv2/MLDv1 +report suppression takes place. This feature is disabled by default. + +The initial patch and idea is from Felix Fietkau. + +Signed-off-by: Felix Fietkau <nbd@nbd.name> +[linus.luessing@c0d3.blue: various bug + style fixes, commit message] +Signed-off-by: Linus Lüssing <linus.luessing@c0d3.blue> +--- + +--- a/include/linux/if_bridge.h ++++ b/include/linux/if_bridge.h +@@ -46,6 +46,7 @@ struct br_ip_list { + #define BR_LEARNING_SYNC BIT(9) + #define BR_PROXYARP_WIFI BIT(10) + #define BR_MCAST_FLOOD BIT(11) ++#define BR_MULTICAST_TO_UNICAST BIT(12) + + #define BR_DEFAULT_AGEING_TIME (300 * HZ) + +--- a/include/uapi/linux/if_link.h ++++ b/include/uapi/linux/if_link.h +@@ -319,6 +319,7 @@ enum { + IFLA_BRPORT_MULTICAST_ROUTER, + IFLA_BRPORT_PAD, + IFLA_BRPORT_MCAST_FLOOD, ++ IFLA_BRPORT_MCAST_TO_UCAST, + __IFLA_BRPORT_MAX + };

To +support such cases we need to first create normal flash device +partitions and then take care of these special ones. + +It's very common case for home routers. Depending on the vendor there +are formats like TRX, Seama, TP-Link, WRGG & more.

Supporting such poor formats +is highly unlikely to be the top priority so these changes try to +minimize maintenance cost to the minimum. It reuses existing code for +these new parsers and just adds a one property and one new function. + +This implementation requires setting partition parsers in a flash +parser.
