Here is my node func.
VLIB_REGISTER_NODE( ip4_timer_test_node) = {
.function = ip4_timer_test_process,
.type = VLIB_NODE_TYPE_PROCESS,
.name = "ip4-timer-test-process",
.state = VLIB_NODE_STATE_POLLING,
};
Regards,
Ewan

主题： [vpp-dev] send packet in vpp
Hi， all
I would like to send packet in timer func, and i followed func "send_dhcp_pkt"
to build a frame.
But the packet did not come out through nic.
Bellow is my func, ping works between those two ip addresses, is there anything
missed, any tools could help me? thanks.
void
ip4_time_out(void)
{
u32 radlen;
u32 * to_output;
u32 bi0;
vlib_buffer_t *b0;
vlib_frame_t *f;
unsigned char *rad0 = NULL;
ip4_header_t *ip40;
udp_header_t *udp0;
vlib_main_t * vm = vlib_get_main();
/* speculatively enqueue b0 to the current next frame */
if (vlib_buffer_alloc (vm, &bi0, 1) == 1)
{
b0 = vlib_get_buffer (vm, bi0);
vnet_buffer(b0)->sw_if_index[VLIB_RX] = 1;
vnet_buffer(b0)->sw_if_index[VLIB_TX] = ~0;
f = vlib_get_frame_to_node (vm, ip4_lookup_node.index);
to_output = vlib_frame_vector_args (f);
to_output[0] = bi0;
f->n_vectors = 1;
vlib_put_frame_to_node(vm, ip4_lookup_node.index, f);
vlib_buffer_advance(b0, sizeof(ethernet_header_t));
ip40 = vlib_buffer_get_current (b0);
vlib_buffer_advance (b0, sizeof (*ip40));
udp0 = vlib_buffer_get_current (b0);
vlib_buffer_advance (b0, sizeof (*udp0));
rad0= vlib_buffer_get_current (b0);

strcpy((char*)rad0,

udp0->checksum = ip4_tcp_udp_com_checksum (vm, b0);
ip40->length = clib_host_to_net_u16 (radlen + sizeof (ip4_header_t) + sizeof
