Subject: [PATCH net-next v1] net: stmmac: Default DWMAC_MOTORCOMM to m on MACH_LOONGSON64
Date: Tue, 15 Sep 2026 15:32:06 +0800 [thread overview]
Message-ID: <20260915073206.6665-1-yangtiezhu@loongson.cn> (raw)
Currently, there is no network connectivity when upgrading to the
latest upstream mainline kernel on certain Loongson machines such
as Loongson-3C6000 server, because the driver for the onboard NIC
is not enabled.
Enable the Motorcomm PCI DWMAC driver as a module by default when
building for the Loongson-64 platform.
This ensures out-of-the-box support for Motorcomm YT6801 Ethernet
controllers on Loongson machines, enabling demand-loading without
increasing the core kernel image size.
