dpsw_if_get_link_state(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the dpsw_if_get_link_state(9) page from the Kernel API Manual — yes that's the whole title, we're being official today 💅. This one's a tiny little function with a big job: it tells you whether a link is up or down. That's it. That's the whole vibe. Let me walk you through it 🫶

✨ SYNOPSIS ✨

int dpsw_if_get_link_state (struct fsl_mc_io *mc_io , u32 cmd_flags ,
u16 token , u16 if_id , struct dpsw_link_state *state );

five arguments, one int coming back at you, no cap 🌸

🎀 ARGUMENTS 🎀

  • mc_io — pointer to the MC portal's I/O object, iykyk 🦋
  • cmd_flags — the command flags, and it's one or more of 'MC_CMD_FLAG_' (plural besties, you can stack 'em)
  • token — token of the DPSW object 🔑
  • if_id — the interface id, literally which interface you're asking about
  • state — the link state: 1 means linkup, 0 means link down or disconnected. main character values only 👑
ngl, that state pointer has to be somewhere for the answer to land, so hand it a valid struct dpsw_link_state * and let it cook 🍓

🌈 RETURN 🌈

the original page leaves this section empty — nothing listed, no return values spelled out 🙈 i'm not gonna invent any for you, so just know the page itself is silent here. (the synopsis does say it returns int, so there's that at least ✨)

🦋 SEE ALSO 🦋

okay this is the part where the whole friend group shows up, and yes i'm listing every single one of them because they all matter 💜

Kernel file: ./drivers/net/ethernet/freescale/dpaa2/dpsw.c

and that's the page bestie!! source/version situation is that truncated kernel path ./drivers/net/ethernet/freesca... and the date is October 2026, brought to you by the dpsw_if_get_link_state(9) girlies 🎀 go check your link state, slay, periodt 💅
