💅 efx_ethtool_fill_self_tests(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a little kernel-side helper and honestly it's giving "one function to rule them all" energy 👑

---

🌸 NAME 🌸

efx_ethtool_fill_self_tests — get self-test details 🧚

---

✨ SYNOPSIS ✨

int efx_ethtool_fill_self_tests (struct efx_nic *efx , struct
       efx_self_tests *tests , u8 *strings , u64 *data );

---

🎀 ARGUMENTS 🎀

• efx — the efx NIC 🖥️ like, the actual network interface card in question, no cap.
• tests — the efx self-test results structure, or NULL if you're not about that life 🙈
• strings — the ethtool strings, or NULL (same deal, optional bestie) 🧵
• data — the ethtool test results, or NULL — you can absolutely pass nothing here and it's fine 💜

---

🔥 DESCRIPTION 🔥

So what does it actually do? It gets the self-test number of strings, the strings, and/or the test results. Pick your fighter 💅 You get back the number of strings — and lowkey the tea is that number is == the number of test results 👑

The reason for merging these three functions is to make sure that they can never be inconsistent. fr fr, that's the whole point — one function, zero chance of two of them drifting apart and lying to each other 😭 iconic design honestly
