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).
