Field Documentation

union { ... }

Next hop after ip4-lookup.

adj_midchain_fixup_t ip_adjacency_t_::fixup_func

A function to perform the post-rewrite fixup.

Definition at line 235 of file lookup.h.

struct { ... } ip_adjacency_t_::glean

IP_LOOKUP_NEXT_GLEAN.

Glean the address to ARP for from the packet's destination

vnet_link_t ip_adjacency_t_::ia_link

Definition at line 199 of file lookup.h.

u8 ip_adjacency_t_::ia_nh_proto

Definition at line 200 of file lookup.h.

fib_node_t ip_adjacency_t_::ia_node

Definition at line 256 of file lookup.h.

u32 ip_adjacency_t_::if_address_index

u16 ip_adjacency_t_::lookup_next_index_as_int

Definition at line 184 of file lookup.h.

u16 ip_adjacency_t_::mcast_group_index

~0 => normal behavior

Definition at line 191 of file lookup.h.

struct { ... } ip_adjacency_t_::midchain

IP_LOOKUP_NEXT_MIDCHAIN.

A nbr adj that is also recursive. Think tunnels. A nbr adj can transition to be of type MDICHAIN so be sure to leave the two structs with the next_hop fields aligned.

u16 ip_adjacency_t_::n_adj

Number of adjecencies in block.

Greater than 1 means multipath; otherwise equal to 1.

Definition at line 179 of file lookup.h.

struct { ... } ip_adjacency_t_::nbr

IP_LOOKUP_NEXT_ARP/IP_LOOKUP_NEXT_REWRITE.

neighbour adjacency sub-type;

The next DPO to use.

Definition at line 231 of file lookup.h.

ip46_address_t ip_adjacency_t_::next_hop

The recursive next-hop.

Definition at line 209 of file lookup.h.

ip46_address_t ip_adjacency_t_::receive_addr

Definition at line 243 of file lookup.h.

u16 ip_adjacency_t_::saved_lookup_next_index

Highest possible perf subgraph arc interposition, e.g.

for ip6 ioam

Definition at line 194 of file lookup.h.

union { ... } ip_adjacency_t_::sub_type

u32 ip_adjacency_t_::tx_function_node

The node index of the tunnel's post rewrite/TX function.
