✨ NAME ✨

ef4_fill_test — fill in an individual self-test entry 🫶

---

🌸 SYNOPSIS 🌸

void ef4_fill_test (unsigned int test_index , u8 *strings , u64 *data ,
int *test , const char *unit_format , int unit_id , const
char *test_format , const char *test_id );

like, that's the whole signature. it returns void, so don't go looking for a return value, there isn't one, periodt. 💅

🦋 ARGUMENTS 🦋

• test_index — the index of the test. which test are we filling in? this one. 🎯
• strings — the Ethtool strings, or NULL. yes, NULL is a valid vibe here.
• data — the Ethtool test results, or NULL. same energy.
• test — pointer to the test result. heads up bestie: this is only used if data != NULL. if data is NULL, this one's just sitting there, unbothered. 💀
• unit_format — the unit name format, e.g. "chan".
• unit_id — the unit id, e.g. 0 for "chan0". 🔢
• test_format — the test name format, e.g. "loopback.tx.sent".
• test_id — the test id, e.g. "PHYXS" for "loopback.PHYXS.tx_sent".

🔥 DESCRIPTION 🔥

fill in an individual self-test entry. that's it. that's the whole description. she's a one-job icon and she ate. 👑

ngl, this function is giving "small but essential." it's not doing the whole self-test suite, it's just the one entry — know the difference, iykyk. ✨
