Altobeam (Altobeam Technologies) is a fabless semiconductor company that designs and markets high-performance WiFi chipsets. They are particularly well-known for manufacturing WiFi modules used in Smart TVs, Set-Top Boxes (STBs), IoT (Internet of Things) devices, and various USB WiFi adapters.

Because Altobeam chips are often embedded inside devices sold under different brand names (like generic USB dongles or smart home gadgets), users often encounter hardware that uses an Altobeam chipset without realizing it until they look at the Device Manager in Windows.

Open core/atbm_netdev.c and find:

Replace with:

.ndo_change_mtu = atbm_change_mtu,

Why? The kernel removed eth_change_mtu in 5.15.
