v9: - There is no tx completion interrupts to free DMAd Tx packets, it means taht we rely on new tx packets arriving to run the destructors of completed packets, which open up space in their sockets's send queues. Sometimes we don't get such new packets causing Tx to stall, a single UDP transmitter is a good example of this situation, so we need a clean up workqueue to reclaims completed packets, the workqueue will only free the last packets which is already stay for several jiffies. Also fix some format cleanups. v8: - Use poll to reclaim xmitted buffer as workaround since no tx done interrupt v7: - Remove select NET_CORE in 0002 v6: - Suggest by Russell: Use netdev_sent_queue & netdev_completed_queue to solve latency issue Also shorten the period of timer, which is used to wakeup the queue since no tx completed interrupt. v5: no big change, fix typo v4: - Modify accoringly to the suggetion from Arnd, Florian, Eric, David Use of_parse_phandle_with_fixed_args & syscon_node_to_regmap get ppe info Add skb_orphan() and tx_timer for reclaim since no tx_finished interrupt Update timeout, and move of_phy_connect to probe to reuse open/stop v3: - Suggest from Arnd, use syscon & regmap_write/read to replace static void __iomem *ppebase. Modify hisilicon-hip04-net.txt accrordingly to suggestion from Florian and Sergei. v2: - Got many suggestions from Russell, Arnd, Florian, Mark and Sergei Remove memcpy, use dma_map/unmap_single, use dma_alloc_coherent rather than dma_pool, etc. Refer property in ethernet.txt, change ppe description, etc. Zhangfei Gao (3): Documentation: add Device tree bindings for Hisilicon hip04 ethernet net: hisilicon: new hip04 MDIO driver net: hisilicon: new hip04 ethernet driver .../bindings/net/hisilicon-hip04-net.txt | 88 +++ drivers/net/ethernet/hisilicon/Kconfig | 9 + drivers/net/ethernet/hisilicon/Makefile | 1 + drivers/net/ethernet/hisilicon/hip04_eth.c | 876 +++++++++++++++++++++ drivers/net/ethernet/hisilicon/hip04_mdio.c | 186 +++++ 5 files changed, 1160 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/hisilicon-hip04-net.txt create mode 100644 drivers/net/ethernet/hisilicon/hip04_eth.c create mode 100644 drivers/net/ethernet/hisilicon/hip04_mdio.c -- 1.8.0 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
