* tcp: use TS opt on RTTs for congestion controlYuchung Cheng2017-06-021-7/+8
| | | | | | | | | | | | | | | | | | Currently when a data packet is retransmitted, we do not compute an RTT sample for congestion control due to Kern's check. Therefore the congestion control that uses RTT signals may not receive any update during loss recovery which could last many round trips. For example, BBR and Vegas may not be able to update its min RTT estimation if the network path has shortened until it recovers from losses. This patch mitigates that by using TCP timestamp options for RTT measurement for congestion control. Note that we already use timestamps for RTT estimation.

This driver is the continuation of the sun8i-emac driver. During the development, it appeared that in fact the hardware was a modified version of some dwmac. So the driver is now written as a glue driver for stmmac. It supports 10/100/1000 Mbit/s speed with half/full duplex. It can use an internal PHY (MII 10/100) or an external PHY via RGMII/RMII. This patch series enable the driver only for the H3/A64/H5 SoC since A83T doesn't have the necessary clocks present in mainline. The driver have been tested on the following boards: - H3 Orange PI PC, BananaPI-M2+ - A64 Pine64, BananaPi-M64 - A83T BananaPI-M3 The first two patchs are some mandatory changes for letting dwmac-sun8i be used. The following three patchs add the driver and its documentation. The remaining are DT patch enabling it. Regards Corentin Labbe Changes since v5: - Added DT patch for NanoPi neo - Use the new adjust_link variables (speedxxx/speedmask) - Made the timeout of readl_poll_timeout from 10 to 100ms - Fix sun8i_unpower_phy that could be called twice - Replace phy by phy-handle in doc/dwmac-sun8i.txt Changes since v4: - Re-ordered by alphabetical order some DT nodes - Simplified power/unpower_phy functions by testing the use of internal_phy - Added a patch for adding dwmac-sun8i to arm64 defconfig - Fix a typo in sun50i-a64-system-controller (wrongly used sun8i) - Reworked uc/mc filter address setting Changes since v3: - Renamed tx-delay/rx-delay to tx-delay-ps/rx-delay-ps - fix syscon compatible example - Changed parameter type for setup() function - Dropped some DT patchs for boards which I could not test further Changes since v2: - corrected order of syscon compatible - added compatible = "ethernet-phy-ieee802.3-c22 to PHY - added set_mac function Changes since v1: - added TX/RX delay units - splitted syscon documentation in its own patch - regulator is now disabled after clk_prepare_enable(gmac->tx_clk) error - Fixed a memory leak on mac_device_info - Use now generic pin config for all DT stuff - CONFIG_DWMAC_SUN8I is now set to y in defconfigs ==================== Signed-off-by: David S.
