Macro Definition Documentation

◆ GNRC_NETIF_FLAGS_6LN

#define GNRC_NETIF_FLAGS_6LN (0x00001000U)

This interface represents a 6Lo node (6LN) according to RFC 6775.

See also: RFC 6775, section 2

Definition at line 132 of file flags.h.

◆ GNRC_NETIF_FLAGS_6LO

#define GNRC_NETIF_FLAGS_6LO (0x00002000U)

6Lo is activated for this interface

Note: Most devices supporting 6Lo actually require 6Lo so this flag should not be configurable for them. As a consequence, this flag must only be changed by a NETOPT_6LO message to the interface.

Definition at line 142 of file flags.h.

◆ GNRC_NETIF_FLAGS_6LO_ABR

#define GNRC_NETIF_FLAGS_6LO_ABR (0x00000200U)

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

Definition at line 109 of file flags.h.

◆ GNRC_NETIF_FLAGS_6LO_BACKBONE

#define GNRC_NETIF_FLAGS_6LO_BACKBONE (0x00000800U)

Interface supports 6LoWPAN general header compression.

Attention: 6CIO (which propagates this flag throughout) not implemented yet

See also: RFC 7400, section 3.3; [draft-ietf-6lo-rfc6775-update-09, section 6.3] (https://tools.ietf.org/html/draft-ietf-6lo-rfc6775-update-09#section-6.3)

Definition at line 125 of file flags.h.

◆ GNRC_NETIF_FLAGS_6LO_HC

#define GNRC_NETIF_FLAGS_6LO_HC (0x00000100U)

This interface uses 6Lo header compression.

See also: RFC 6282

Definition at line 104 of file flags.h.

◆ GNRC_NETIF_FLAGS_6LO_MESH

#define GNRC_NETIF_FLAGS_6LO_MESH (0x00000400U)

◆ GNRC_NETIF_FLAGS_HAS_L2ADDR

#define GNRC_NETIF_FLAGS_HAS_L2ADDR (0x00000001U)

◆ GNRC_NETIF_FLAGS_IPV6_ADV_O_FLAG

#define GNRC_NETIF_FLAGS_IPV6_ADV_O_FLAG (0x00000080U)

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.

DNS-related information)
