ixgbe_add_sanmac_netdev(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_add_sanmac_netdev 💖

okay so bestie, this is a page from the Kernel API Manual and it's about one very specific little function in the ixgbe driver. it's short, it's sweet, it's giving "one job and it does it" energy. let's get into it 🫶

✨ NAME ✨

ixgbe_add_sanmac_netdev — adds the SAN MAC address to the corresponding netdev->dev_addrs

like, that's literally the whole thing. it takes the SAN MAC and sticks it onto that net_device's dev_addrs list. no cap, that's the vibe. 💅

🌸 SYNOPSIS 🌸

int ixgbe_add_sanmac_netdev (struct net_device *dev );

🦋 ARGUMENTS 🦋

  • dev — the network interface device structure 👑 (this is the net_device we're doing the SAN MAC thing for)

🎀 DESCRIPTION 🎀

Returns non-zero on failure.

that's it. that's the description. short king behavior honestly 😭 — so like, keep an eye on the return value, because if it comes back non-zero, something went sideways, and you should not ignore it. periodt. ⭐

🔥 SEE ALSO 🔥

first up, the actual source file this lives in — go read it, it's iconic:

  • Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_main.c

and then the whole friend group 🫶 (this function does not roll alone, clearly):

ngl bestie, ixgbe_del_sanmac_netdev(9) right there in the list is the obvious partner-in-crime — add it, delete it, balance restored 🧚

and that's the whole page, she's done, go forth and add those SAN MACs 💜

sign-off time: this came out of ./drivers/net/ethernet/intel/i... (yeah the path got cut off, that's how it shipped, don't come for me 🙈) and the date on it is October 2026. mwah 💋
