flags.h

Flag definitions for Network interface API.

enum @190
GNRC_NETIF_AAC_NONE = 0
no configuration
GNRC_NETIF_AAC_AUTO

Use some automatic bootstrapping (e.g.

SLAAC with IPv6)

GNRC_NETIF_AAC_DHCP
Use DHCP(v6)
GNRC_NETIF_FLAGS_HAS_L2ADDR

Network interface has link-layer address. 

1
(0x00000001U)

There are link-layers (e.g. SLIP) that do not have (nor require) link-layer addresses. This flag signifies this fact to upper layers by leaving it unset.

GNRC_NETIF_FLAGS_IPV6_FORWARDING

Network interface is enabled for IPv6 forwarding. 

1
(0x00000002U)
GNRC_NETIF_FLAGS_IPV6_RTR_ADV

Network interface advertises itself as an IPv6 router (implies flags.h::GNRC_NETIF_FLAGS_IPV6_FORWARDING to be set) 

1
(0x00000004U)
GNRC_NETIF_FLAGS_IPV6_ADV_MTU

This interface advertises its gnrc_netif_t::mtu to other nodes (implies flags.h::GNRC_NETIF_FLAGS_IPV6_RTR_ADV to be set) 

1
(0x00000008U)
GNRC_NETIF_FLAGS_IPV6_ADV_CUR_HL

This interface advertises its gnrc/netif.h::gnrc_netif_t::cur_hl to other nodes (implies flags.h::GNRC_NETIF_FLAGS_IPV6_RTR_ADV to be set) 

1
(0x00000010U)
GNRC_NETIF_FLAGS_IPV6_ADV_REACH_TIME

This interface advertises its reachable time to other nodes (implies flags.h::GNRC_NETIF_FLAGS_IPV6_RTR_ADV to be set) 

1
(0x00000020U)
GNRC_NETIF_FLAGS_IPV6_ADV_RETRANS_TIMER

This interface advertises its retransmission timer to other nodes (implies flags.h::GNRC_NETIF_FLAGS_IPV6_RTR_ADV to be set) 

1
(0x00000040U)
GNRC_NETIF_FLAGS_IPV6_ADV_O_FLAG

If gnrc_netif_t::ipv6::aac_mode == GNRC_NETIF_AAC_DHCP then this flag indicates that other configuration information is available via DHCPv6 (e.g. 

1
(0x00000080U)

DNS-related information)

GNRC_NETIF_FLAGS_6LO_ABR

This interface acts as a 6Lo border router to the LLN. 

1
(0x00000200U)
GNRC_NETIF_FLAGS_6LO_MESH

This interface acts as a mesh-under node (route-over topology when unset) 

1

1
(0x00006000U)
GNRC_NETIF_FLAGS_MAC_RX_STARTED

Flag to track if a transmission might have corrupted a received packet. 

1
(0x00008000U)
