💖 KSZ8995MA 💖

okay bestie, gather round, because this is the ksz8995ma page from section 4 of the Kernel Interfaces Manual, and honestly? it's giving hardware girlie. ✨

🌸 NAME 🌸

ksz8995ma — the driver for the Micrel KSZ8995MA fast ethernet switch chip. yes that's a whole switch chip, in your kernel, being iconic. 🔥

🎀 SYNOPSIS 🎀

okay so this is how you pull up:

device spibus
device etherswitch
device ksz8995ma

hint.ksz8995ma.0.at="spibus0"

that's it. that's the whole vibe. copy it exactly, no freestyling. 💅

✨ DESCRIPTION ✨

so like, the ksz8995ma device driver hands you a management interface to the Micrel KSZ8995MA fast ethernet switch chip. 🦋

this driver uses the spi interface. no cap.

now listen, the KSZ8995 series has so many versions — like, way too many, main character energy for real — but this driver only supports the MA/FQ version. only those two. the rest are not invited to the party. 🙈

what does it actually support tho? glad you asked:

  • port support 💖
  • dot1q vlan support 💖

and with dot1q, it supports port base tag/untag. so you can tag or untag per port, periodt.

🌈 EXAMPLES 🌈

setting up dot1q vlan

you do it with the etherswitchcfg command, like this:

# etherswitchcfg config vlan_mode dot1q

that's the whole thing. vlan_mode dot1q. slay. ✨

making port 5 a tagging port

# etherswitchcfg port5 addtag

boom. port 5 is now the tagging port. she's got a job now. 💅

👑 SEE ALSO 👑

go read those too bestie, they're the supporting cast and they ate. 🫶
