This made the DMA linked list queue -the traffic of each MAC on a different internal queue. However during long -term testing we found that this will cause traffic stalls as the multi -queue setup requires a more complete initialisation which is not part of -the upstream driver yet. - -This patch removes the code setting the QID field, resulting in all -traffic ending up in queue 0 which works without any special setup. - -Signed-off-by: John Crispin <blogic@openwrt.org> ---- - drivers/net/ethernet/mediatek/mtk_eth_soc.c | 3 +-- - 1 file changed, 1 insertion(+), 2 deletions(-) - ---- a/drivers/net/ethernet/mediatek/mtk_eth_soc.c -+++ b/drivers/net/ethernet/mediatek/mtk_eth_soc.c -@@ -603,8 +603,7 @@ static int mtk_tx_map(struct sk_buff *sk - WRITE_ONCE(txd->txd1, mapped_addr); - WRITE_ONCE(txd->txd3, (TX_DMA_SWC | - TX_DMA_PLEN0(frag_map_size) | -- last_frag * TX_DMA_LS0) | -- mac->id); -+ last_frag * TX_DMA_LS0)); - WRITE_ONCE(txd->txd4, 0); - - tx_buf->skb = (struct sk_buff *)MTK_DMA_DUMMY_DESC; |
