MOS(4) — mos 💅✨

okay so bestie, this whole page is MOS(4), living in the Kernel Interfaces Manual, and it’s all about the mos driver 🫶 pull up a chair.

🌸 NAME 🌸

mos — the Moschip MCS7730/MCS7830/MCS7832 USB Ethernet driver 💖

✨ SYNOPSIS ✨

want this driver baked right into your kernel? drop these lines into your kernel configuration file:

device uhci
device ohci
device ehci
device usb
device miibus
device uether
device mos

or, if you’d rather load the driver as a module at boot time, put this line in loader.conf(5):

if_mos_load="YES"

🦋 DESCRIPTION 🦋

the mos driver has your back for USB Ethernet adapters based on the Moschip MCS7730/MCS7830/MCS7832 chipset 💜

if your adapter has that Moschip MCS7730/MCS7830/MCS7832 chipset inside, it’ll operate at 100Base-TX and full-duplex, periodt.

inside the Moschip is a 10/100 Ethernet MAC with an MII interface, and it’s designed to work with both Ethernet and HomePNA transceivers. even though it’s designed to interface with 100Mbps peripherals, that only works with USB 2.0 — the existing USB 1.0 standard caps the maximum transfer speed at 12Mbps. so if you’re on USB 1.0, please don’t expect to actually hit 100Mbps speeds with these devices, bestie 😭

it supports a 64-bit multicast hash table, a single perfect filter entry for the station address, and promiscuous mode. packets get received and transmitted over separate USB bulk transfer endpoints ✨

for the full config glow-up, see ifconfig(8).
