- Subject: [PATCH] net: mediatek: Fix multicast ICMPv6 for the rt3050 ethernet switch.
- The FCT2 esw register should be set to 0x2500C to have "unknown IPv6
- multicast" packets broadcasted to every port, instead of dropped.
- The previous value only let those packets go through ports 1 and 3.
- "Unknown IPv6 multicast" packets include packets needed by ICMPv6 echo
- requests addressed to well-known addresses, such as ff02::1 (MAC address
- is 33:33:00:00:00:01 in this case).
