This series fixes multiple issues related to the L2 table and multicast table. That includes an issue that causes corruption of the port mask for unknown multicast forwarding, which can occur even when multicast snooping is disabled.
With these patches, multicast snooping should be mostly working. However, one important missing piece is forwarding of all multicast traffic to multicast router ports (as specified in section 2.1.2-1 of RFC4541). As far as I can see, this is a general issue that affects all DSA switches, and cannot be fixed without changes to the DSA subsystem. Jan Hoffmann (6): realtek: fix writing/deletion of CAM entries realtek: don't return 0 from rtl83xx_mc_group_alloc on failure realtek: don't treat first multicast portmask entry as reserved realtek: actually remove port from multicast portmask realtek: don't add CPU port to multicast portmasks realtek: remove store_mcgroups/load_mcgroups .../files-5.10/drivers/net/dsa/rtl83xx/dsa.c | 49 +++---------------- .../drivers/net/dsa/rtl83xx/rtl838x.h | 1 - .../files-5.15/drivers/net/dsa/rtl83xx/dsa.c | 45 +++-------------- .../drivers/net/dsa/rtl83xx/rtl838x.h | 1 - 4 files changed, 16 insertions(+), 80 deletions(-) -- 2.39.1 _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
