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
◆ 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.
◆ 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
◆ GNRC_NETIF_FLAGS_6LO_HC
| #define GNRC_NETIF_FLAGS_6LO_HC (0x00000100U) |
◆ 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)
