I've ported mue(4), driver for Microchip LAN75xx/LAN78xx known as internal NIC of Raspberry Pi 3B+, from OpenBSD.
Here's source codes as well as patch for other parts of kernel: http://www.NetBSD.org/~rin/mue20180825 The driver has been tested on following devices: - Raspberry Pi 3B+ (LAN7800) - Z-TEK ZE582 (LAN7500) on both RPI3b+ and ThinkPad X60 (amd64) dmesg and performance on RPI3b+ are as follows: % dmesg ... mue0 at uhub2 port 1 mue0: SMSC (0x424) LAN7800 USB 3.1 gigabit ethernet device (0x7800), rev 2.10/3.00, addr 7 mue0: LAN7800 mue0: Ethernet address xx:xx:xx:xx:xx:xx ukphy0 at mue0 phy 1: OUI 0x00800f, model 0x0013, rev. 2 ukphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto ... % scp somewhere:random.128m . random.128m 100% 128MB 12.4MB/s 14.1MB/s 00:10 % scp random.128m somewhere: random.128m 100% 128MB 9.1MB/s 9.3MB/s 00:14 Basically, the driver works fine. However, if the media type is set to something other than 1000baseT-FDX, data transmission becomes quite unstable. Also, ukphy(4) mistakenly recognize 1000baseT as a supported media type, although the adapters do not support it. I suspect that MII of the adapters has bugs... I thank ryo@ for letting me know how to obtain MAC address from bcmmbox(4). I'd like to commit it in this weekend if there's no objection. Thanks, rin
