Fields

family: u8

input: network family for lookup (AF_INET, AF_INET6) output: network family of egress nexthop

l4_protocol: u8

set if lookup is to consider L4 data - e.g., FIB rules

sport: be16_tdport: be16_ttot_len: u16

total length of packet from network header - used for MTU check

ifindex: u32

input: L3 device index for lookup output: device index from FIB lookup

inputs: bpf_fib_lookup_inputs_tsrc: bpf_fib_lookup_addr_tdest: bpf_fib_lookup_addr_t

input to bpf_fib_lookup, ipv{4,6}_dst is destination address in network header. output: bpf_fib_lookup sets to gateway address if FIB lookup returns gateway route

h_vlan_proto: be16_t

output

h_vlan_tci: be16_tsmac: [u8; 6]
