Currently we will not update the receive descriptor tail pointer in stmmac_rx_refill. Rx dma will think no available descriptors and stop once received packets exceed DMA_RX_SIZE, so that the rx only test will fail. Update the receive tail pointer in stmmac_rx_refill to add more descriptors to the rx channel, so packets can be received continually Fixes: 54139cf3bb33 ("net: stmmac: adding multiple buffers for rx") Signed-off-by: Biao Huang <biao.huang@mediatek.com> --- drivers/net/ethernet/stmicro/stmmac/stmmac_main.c | 1 + 1 file changed, 1 insertion(+)
