This is a second RFC version of the DSA driver for Realtek RTL8366x especially RTL8366RB.
I've been beating my head against this one and I'm not really clear on why my ethernet frames are not coming through to the CPU port on the chip. It appears when using ethtool -S on the ports that packets are passing fine into the router fabric and through to the CPU port but the ethernet driver where the fixed link is connected refuse to accept the packages. Of course packages needs VLAN tagging/untagging, this is not the problem as it seems. The OpenWRT userspace even kicks the interface in promiscuous mode so all packages should be accepted, I also tried tcpdump on the interface to no avail: the ethernet frames are so broken that they do not even make it through the fixed link. The do cause error statistics on the ethernet port on the system side. It might very well be that the problem is on the ethernet driver side, and this driver "just works" with other routers, so reposting it along with the DTS example so others can try it while I keep banging my head against it. Maybe I should just try to obtain another router with this chip so as to establish that it is not the DSA router driver that is wrong. I did try this hardware with the present OpenWRT driver (not DSA) and that failed too. Anyways check out the new DT bindings etc. Linus Walleij (4): net: phy: realtek: Support RTL8366RB variant net: dsa: Add bindings for Realtek SMI DSAs net: dsa: realtek-smi: Add Realtek SMI driver ARM: dts: Add ethernet and switch to D-Link DIR-685 .../bindings/net/dsa/realtek-smi.txt | 153 ++ arch/arm/boot/dts/gemini-dlink-dir-685.dts | 153 +- drivers/net/dsa/Kconfig | 12 + drivers/net/dsa/Makefile | 2 + drivers/net/dsa/realtek-smi.c | 488 ++++++ drivers/net/dsa/realtek-smi.h | 146 ++ drivers/net/dsa/rtl8366.c | 524 ++++++ drivers/net/dsa/rtl8366rb.c | 1411 +++++++++++++++++ drivers/net/phy/realtek.c | 33 + 9 files changed, 2921 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/net/dsa/realtek-smi.txt create mode 100644 drivers/net/dsa/realtek-smi.c create mode 100644 drivers/net/dsa/realtek-smi.h create mode 100644 drivers/net/dsa/rtl8366.c create mode 100644 drivers/net/dsa/rtl8366rb.c -- 2.17.0 _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org http://lists.infradead.org/mailman/listinfo/openwrt-devel
