    net/zxdh: optimize Tx performance
    
    1. Rework the Tx completion flush to walk descriptors one at a time and
       free each completed segment with rte_pktmbuf_free_seg(), add prefetch
       hints on the next descriptor cache line, switch the ring-held mbufs
       in zxdh_dev_free_mbufs() to rte_pktmbuf_free_seg().
    
    2. The flush drives the inner do/while off the device-returned
       `desc[used_idx].id` (last segment's index for a chain): iterates
       once on the push path, walks every segment of a chain on the
       append path and frees each segment's cookie via
       `vq->vq_descx[used_idx].cookie`. The flush also rewrites
       `desc[used_idx].id = used_idx`; this is redundant given that the
       enqueue paths already set the id, but is kept for commercial
       alignment.
    
    3. Guard the walk with a `budget` counter initialised to `vq_nentries`,
       break on `id >= size`, and mask the prefetch index with `(size - 1)`
       so the walk and `free_cnt` stay bounded even if the device writes
       an out-of-range or stale id.
    
    4. Document the Tx xmit changes in the 26.11 release notes.
