Subject: RE: [PATCH v2] net: usb: ax88179_178a: avoid writing the mac address before first reading

Hello,
I am using a TP-Link UE306 USB Ethernet adapter. The kernel detects it as an ASIX AX88179A USB Ethernet adapter. When using a different MAC address than the adapter's own (i.e. MAC address randomization), I am unable to send or receive packets unless set to promiscuous mode.
I am using NetworkManager to manage my connections. When I set 802-3-ethernet.cloned-mac-address to the device's MAC address in the connection settings (i.e. `nmcli con edit), the device works as expected. When that property is not set (null value), the device is only able to receive packets when set to promiscuous mode.
uname -a output: Linux hostname 6.8.8-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 28 Apr 2024 18:53:26 +0000 x86_64 GNU/Linux
This is Arch Linux's kernel. The patches applied are here: <https://github.com/archlinux/linux/releases/tag/v6.8.8-arch1>
