Though the SparX-5i can control IPv4/6 multicasts separately from non-IP
multicasts, these are all muxed onto the bridge's BR_MCAST_FLOOD flag.

Since Protonmail apparently caused issues with certain email clients
I have now switched to using gmail. Hopefully, there will be no issues
this time.

Changes in v2:
 - Added SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS callback
