However, a firmware crash occurs during this reinjection process. The issue arises because the driver populates peer metadata in reo_ent_ring->queue_addr_lo, while the firmware expects the physical address obtained from the corresponding peer’s queue descriptor. Fix it by filling peer's queue descriptor's physical address in queue_addr_lo.
