💅 i40e_ddp_does_profile_overlap — NAME ✨

ok so bestie, this is the page for i40e_ddp_does_profile_overlap — and what it does is literally right there in the name: it checks if a DDP profile overlaps with an existing one. that's it, that's the whole gig 💖 (also hey, this is the Kernel API Manual, welcome to the group chat 🫶)

🌸 SYNOPSIS 🌸

int i40e_ddp_does_profile_overlap (struct i40e_hw *hw , struct
       i40e_profile_info *pinfo );

🎀 ARGUMENTS 🎀

  • hw — the HW data structure 👑 like, the hardware's whole identity, okurr
  • pinfo — the DDP profile information structure 🦋 this is the profile you're asking about

⭐ DESCRIPTION ⭐

so what it actually does: it checks if the DDP profile overlaps with an existing one. vibe check on your profile, basically 💅

and the return value is doing the most, so listen up:

  • returns >0 if the profile overlaps 😭 (not the moment, bestie)
  • returns 0 if the profile is ok ✨ slay, no notes
  • returns <0 if there's an error 💀
lowkey important: those are three very different outcomes, so don't just check for truthy/falsy — >0 and <0 mean completely different things fr fr 🙈
