Hi,
I believe you missed configuring vnet_hw_if_tx_frame_t for that frame.

Hi,
I am facing a crash in the below code. It's 12 worker/1 core setup.
we are using bit old VPP - 20.09.
function under suspect is ---
buffer_send_to_node()
1. vlib_frame_t *frame;
2. u32 *to_next;
3.
4. frame = vlib_get_frame_to_node (vm, node_index);
5. frame->n_vectors = 1;
6. to_next = vlib_frame_vector_args (frame);
7.
8. to_next[0] = buffer_index;
9.
10. vlib_put_frame_to_node (vm, node_index, frame );
11. return;
The crash is seen at

Can an allocated frame at line 4 be freed via dispatch_pending_node in
any conditions ?
