NET_IGMP_ERR_INVALID_ADDR_GRP
NET_IGMP_ERR_HOST_GRP_NONE_AVAIL
NET_IGMP_ERR_HOST_GRP_INVALID_TYPE
NET_IF_ERR_INVALID_IF

Required Configuration

Available only if NET_MCAST_CFG_IPv4_RX_EN is enabled (see section Network Stack Configuration).

IGMP is the protocol used for multicast communication with IPv4. Therefore, IGMP can be used only if NET_IPv4_CFG_EN is also enabled (see section Network Stack Configuration). 

Notes / Warnings

addr_grp must be in host-order.
