Use an xdp_frame structure for managing the frame. Store a backpointer to the structure at the start of the buffer before enqueueing for cleanup on TX confirmation. Reserve DPAA_TX_PRIV_DATA_SIZE bytes from the frame size shared with the XDP program for this purpose. Use the XDP API for freeing the buffer when it returns to the driver on the TX confirmation path. The frame queues are shared with the netstack. The DPAA driver is a LLTX driver so no explicit locking is required on transmission. This approach will be reused for XDP REDIRECT.
