Are you sure that you have correct version on USB drive? mdio-tools package is missing.

1668

download and flashed USB again , after boot same out put.

Please check again if you are using correct image: https://github.com/testuser7/openwrt/releases/download/qualcommax-d440c8c/openwrt-qualcommax-ipq807x-linksys_homewrk-initramfs-uImage.itb

I have extracted content and mdio is there.

This is definitely a package from a different version.

1672

Tried NSS build(qualcommax-nss-06036bc) , works ! (i dont know how to check for NSS)
Thanks for including Luci

BTW Thanks to davidlucking for describing the routers - my box says HOMEWRK but the power on screen is the one for MX4300. So I avoid HOMEWRK builds

NSS Offloading for WAN/LAN/WiFi is enabled by default.

If you go to Kernel log, you will see entries like this:

Got the same problem. Found that DHCPOFFER packet contains wrong (partial) UDP checksum thus is dropped by the dhcp client. Fixed by turning off tx checksum offloading for the mesh interface on the primary router:

root@mx4300:~# ethtool --offload phy2-mesh0 tx-checksumming off

Thanks, cable was connected to the port with label lan3 (0x02) or lan1 (0x04)?

@robimarko It seams that registers for phy 0x02 and 0x04 are mixed.
Does this mean that the ports are configured incorrectly in dts:

&mdio {
	status = "okay";

	pinctrl-0 = <&mdio_pins>;
	pinctrl-names = "default";
	reset-gpios = <&tlmm 37 GPIO_ACTIVE_LOW>;

	ethernet-phy-package@0 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "qcom,qca8075-package";
		reg = <0>;

		qca8075_1: ethernet-phy@1 {

It was for sure connected to PHY at 0x4, as that one is the only one with a link-up.

What do you mean by registers are mixed?

1678

Registers changed after cable connection for:

  • MX4300 (registers changed only for phy 0x04)
	0x01	0x02	0x03	0x04
0x1	0x7949	0x7949	0x7949	0x796d
0x5	0x0000	0x0000	0x0000	0xcde1
0x6	0x0004	0x0004	0x0004	0x000f
0xa	0x0000	0x0000	0x0000	0x7800
0xf	0x2000	0x2000	0x2000	0xa000
0x11	0x0010	0x0010	0x0010	0xbc1c
0x13	0x0000	0x0000	0x0000	0x4c00
0x1b	0x0000	0x0000	0x0000	0x063e
0x1f	0x0000	0x0000	0x0000	0x8500
  • HomeWRK (some registers are changed for phy 0x02 and other for phy 0x04)
	0x01	0x02	0x03	0x04
0x1	0x7949	0x796d	0x7949	0x7949
0x5	0x0000	0xcde1	0x0000	0x0000

Wait, can we restart here?

Is MX4300 broken as well?
If not, then I dont see a point in dumping anything from it.

Which port is connected on the HomeWRK (I guess one with PHY at 0x2 because it detected a link)?

1680

MX4300 is OK.

@flyingdida Can you answer?

mdio report that all ports are down even if cable is connected to one of them: OpenWrt support for Linksys MX4200 - #1633 by lytr

1681

And that is extremely weird, since register 0x1 is the generic 802.3 status register and its BIT(2) for link status in 1 and thus it sees a link in the dump you provided.

Even more so, the PHY specific status register (0x11) which always has the current info sees 1G, full-duplex link.

Do note that the MDIO tool only interprets generic 802.3 registers, while the kernel driver (And thus ethtool) will use the PHY specific register instead
