The current CPU sync starts at\ndma_addr and only covers rx_bytes + MVPP2_MH_SIZE bytes, which syncs the\nunused headroom and misses the same number of bytes at the packet tail.\n\nOn non-coherent DMA systems this can leave the CPU reading stale cache\ncontents for the end of the received frame.\n\nUse dma_sync_single_range_for_cpu() with MVPP2_SKB_HEADROOM as the range\noffset so the sync covers the Marvell header and packet data actually\nwritten by hardware.","state":0,"publishedAt":"2026-06-25T08:39:20.186+00:00","modifiedAt":"2026-10-19T19:57:29.347+00:00","affected":[{"ecosystem":"Vendor
