ksz9477_get_..._block_start(9)

💅 ksz9477_get_next_block_start — NAME ✨

ok so this is ksz9477_get_next_block_start, and it lives in the Kernel API Manual (yep, the (9) girlies, section 9, we love her). her whole job? identify the starting index of the next ACL block. that's it. that's the vibe. 🎀

---

🌸 SYNOPSIS 🌸

int ksz9477_get_next_block_start (struct ksz_device *dev , int port ,
       int start );

like, three args, one int back. lowkey elegant ngl 🦋

---

✨ ARGUMENTS ✨

• dev — pointer to the device structure. the main character of the whole struct situation 💖
• port — the port number where the ACL entries are being checked. yes, that port. 🫶
• start — the starting index the search kicks off from. where we begin, bestie. ⭐

---

💫 DESCRIPTION 💫

okay so picture this: the function goes looking for the next valid ACL block, starting from the provided invalid one — or, if it hits the end of the ACL entries without finding another block, it returns the maximum ACL entries count. that's the whole quest. no cap. 🔥

(it's giving "search party but for ACL blocks" and honestly? obsessed. 💅)

---

👑 RETURN 👑

• the starting index of the next valid ACL block 🎀
• KSZ9477_ACL_MAX_ENTRIES if no other valid blocks are found after start 🙈
• a negative error code if an error occurs while checking 😭
