Description Petr Bahula 2023-02-21 12:13:29 UTC
Created attachment 853496 [details]
config of 5.15.80 kernel

After update from gentoo-sources-5.15.80 to gentoo-sources-6.1.12 the USB ETH card AX88179A which is in USB-C dock is not accessible as eth1.
New configuration was made through "make olddefconfig" and
 checked according https://linux-hardware.org/index.php?id=usb:0b95-1790.
In attachment are:
 config.5.15.80 and dmesg.5.15.80 with 5.15.80 kernel and
 config.6.1.12 and dmesg.6.1.12 with 6.1.12 kernel.

Comment 4 Alice Ferrazzi Gentoo Infrastructure gentoo-dev 2023-02-22 01:41:47 UTC
could you do a kernel git bisect?

Comment 5 Petr Bahula 2023-02-22 15:18:47 UTC
    !!! IMPORTANT !!!
If the HW is booted with good kernel and then rebooted (without losing power) to bad kernel, it will still work. Only if it is booted with bad kernel from cold state (total no power) then it will not work.

    net: usb: ax88179_178a: Bind only to vendor-specific interface
    
    The Anker PowerExpand USB-C to Gigabit Ethernet adapter uses this
    chipset, but exposes CDC Ethernet configurations as well as the
    vendor specific one. This driver tries to bind by PID:VID
    unconditionally and ends up picking up the CDC configuration, which
    is supposed to be handled by the class driver. To make things even
    more confusing, it sees both of the CDC class interfaces and tries
    to bind twice, resulting in two broken Ethernet devices.
    
    Change all the ID matches to specifically match the vendor-specific
    interface. By default the device comes up in CDC mode and is bound by
    that driver (which works fine); users may switch it to the vendor
    interface using sysfs to set bConfigurationValue, at which point the
    device actually goes through a reconnect cycle and comes back as a
    vendor specific only device, and then this driver binds and works too.
    
    The affected device uses VID/PID 0b95:1790, but we might as well change
    all of them for good measure, since there is no good reason for this
    driver to bind to standard CDC Ethernet interfaces.

I've reverted changes made in the c67cc4315a8e605ec875bd3a1210a549e3562ddc commit and gentoo-sources-6.1.12 works correctly now.

Sorry I should been more clear.

What's ifconfig -a without the patch ?
