Okay so welcome to SM(4) — the Kernel Interfaces Manual page for the sm driver — and it's giving major Ethernet vibes. 💖 Let me walk you through it, bestie. 💅

✨ NAME ✨

sm — the SMC91Cxx-based Ethernet interfaces device driver. Periodt. 💁‍♀️

🌈 SYNOPSIS 🌈

sm0 at ifpga0 addr 0xb8000000 irq 27
sm0 at isa? port 0x300 irq 10
sm* at mhzc?
sm* at pcmcia? function ?
sm* at nubus?

🦋 DESCRIPTION 🦋

The sm device driver supports SMC91C9x-based and SMC91C1xx-based Ethernet interfaces. No cap, that's the whole vibe. 🌸

Here's the tea on all the different attachments, bestie:

  • ifpga0 attachment — supports SMC91C9x-based Ethernet interface on the ARM Integrator/CP board. Iconic embedded energy. 🫶
  • ISA attachment — supports any SMC91C9x-based Ethernet interface on the ISA bus, including the EFA Info*Express SVC VLB interface, and the on-board SMC91C9x Ethernet found in many embedded PCs and laptop docking stations. The way that it works with all these old-school setups? Literally impressive. 💀
  • mhzc attachment — supports the Megahertz combo Ethernet and modem card. Two-in-one slay. ✨
  • PCMCIA attachment — supports Megahertz X-JACK Ethernet cards. PCMCIA is giving vintage realness and I'm obsessed. 🎀
  • nubus attachment — supports SMC-based Ethernet cards for the macintosh. Retro Mac energy, we love to see it. 🍓

🌟 MEDIA SELECTION 🌟

The SMC91C1xx supports the MII interface, so the list of supported media depends on several factors, including which PHY is attached. The SMC91C9x supports AUI and UTP media types. Facts only. 💅

To enable the AUI media, select the 10base5 or aui media type with ifconfig(8)'s media directive. To select UTP, select the 10baseT or utp media type. You're welcome. 😌

ifconfig(8)'s -m option will display the full list of supported media directives for a particular configuration. So if you're ever confused, just hit that -m and let it spill the tea for you. 🌈

💀 DIAGNOSTICS 💀

sm0: unable to read MAC address from CIS

This indicates that the Ethernet address, which is stored in the CIS information on the Megahertz X-JACK PCMCIA Ethernet card, is corrupted. Not the vibe, but now you know. 😭
