Public bug reported:
The Radxa Router Hat for the Raspberry Pi provides a PCIe bridge with 2
network controllers and and m.2 slot for an NVME driver. The NVMe drive
works fine but kernel support for the NICs is missing.
This is the lspci output:
0001:05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125
2.5GbE Controller (rev 05)
0001:06:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8125
2.5GbE Controller (rev 05)
0002:00:00.0 PCI bridge: Broadcom Inc. and subsidiaries BCM2712 PCIe Bridge
(rev 21)
The RTL8125 is supported by the kernel module r8169 which is missing in
the kernel. The following additional configuration settings are needed:
CONFIG_NET_VENDOR_REALTEK=y
CONFIG_R8169=m
The same settings are enabled on the amd64 kernel.
In the ongoing effort to split the linux-firmware package into smaller
packages, please, ensure that the R8125 firmware is made available for
the Raspberry.
Best regards
Heinrich
