Main DPDK input node.
- Node Identifier:
dpdk-input
This is the main DPDK input node: across each assigned interface, call rte_eth_rx_burst(...) or similar to obtain a vector of packets to process. Handle early packet discard. Derive vlib_buffer_t
metadata from struct rte_mbuf
metadata, Depending on the resulting metadata: adjust b->current_data, b->current_length
and dispatch directly to ip4-input-no-checksum, or ip6-input. Trace the packet if required.
- Parameters
-
- Graph mechanics: buffer metadata, next index usage
Uses:
struct rte_mbuf mb->ol_flags
RTE_ETH_IS_xxx_HDR(mb->packet_type)
- packet classification result
Sets:
b->error
if the packet is to be dropped immediately
b->current_data, b->current_length
- adjusted as needed to skip the L2 header in direct-dispatch cases
vnet_buffer(b)->sw_if_index[VLIB_RX]
vnet_buffer(b)->sw_if_index[VLIB_TX] = ~0
b->flags
- to indicate multi-segment pkts (VLIB_BUFFER_NEXT_PRESENT), etc.
Next Nodes:
- Static arcs to: error-drop, ethernet-input, ip4-input-no-checksum, ip6-input, mpls-input
- per-interface redirection, controlled by
xd->per_interface_next_index
