💅 ice_lag_prepare_vf_reset(9)

okay so this is a page from the Kernel API Manual — yes, the actual kernel man pages, and yes, we're gonna make it cute. Bestie, this is a helper function whose whole vibe is adjusting the VF lag so it's ready for a reset. That's it. That's the job. She's a little support-system icon and we love her for it 🎀

✨ NAME ✨

ice_lag_prepare_vf_reset — the helper that adjusts the VF lag for a reset 🦋

Like, it's not the main character, it's the best friend who shows up with the emotional support and makes sure everything's in place before the big reset moment. Lowkey essential, highkey underrated.

🌸 SYNOPSIS 🌸

u8 ice_lag_prepare_vf_reset (struct ice_lag *lag );

That's the whole signature, periodt. Returns a u8 and takes one pointer to a struct ice_lag. Clean, simple, no drama 💅

🫶 ARGUMENTS 🫶

  • lag — the lag struct for the interface that owns the VF. she's the one carrying all the context, so hand her over correctly, k?

🔥 CONTEXT 🔥

must be called with the lag_mutex lock held.

not me stressing this but FR FR: you MUST be holding the lag_mutex lock when you call this. No cap. Don't skip it, don't get cute with it, just hold the lock. Lock discipline is the vibe check here 🙈

👑 RETURN 👑

Returns the active lport value — or ICE_LAG_INVALID_PORT if nothing moved.

So basically: you get a real port back when something actually changed, and you get ICE_LAG_INVALID_PORT when nothing did. Either way you know what's up ✨
