Dpdk_device_t field description

Lockp send queue lock. When the number of sending queues is less than the number of threads, sending packets to port needs to be locked. Lockp is an array, and each element corresponds to a sending queue, that is, one lock for each sending queue.

Index assigned to port by device_index, one for each port

Vlib_hw_if_index the index of the hw structure corresponding to the port

Vlib_sw_if_index the index of the sw structure corresponding to the port

Per_interface_next_index sets the index of the next node through the plug-in. If this field is not set, the next node is handoff by default.

Tx_vectors packet cache (array), one per thread, each array size is 4096

Rx_vectors packet receiving cache (array), one for each receive queue, each array size is 256,

D_trace_bufferstrace is used to store mbuf arrays
