IPv4 input node.
ip4-input
This is the IPv4 input node: validates ip4 header checksums, verifies ip header lengths, discards pkts with expired TTLs, and sends pkts to the set of ip feature nodes configured on the rx interface.
vm | vlib_main_t corresponding to the current thread |
node | vlib_node_runtime_t |
frame | vlib_frame_t whose contents should be dispatched |
Uses:
b->current_config_index
corresponding to each pkt's rx sw_if_index.vnet_buffer(b)->sw_if_index[VLIB_RX]
sw_if_index
value of the interface that the packet was received on.Sets:
vnet_buffer(b)->ip.adj_index[VLIB_TX]
Next Indices:
vnet_get_config_data (... &next0 ...);
or error-drop
