hinic_hwdev_cb_register(9)

💅 hinic_hwdev_cb_register(9) — like, the Kernel API Manual era 🎀

okay so bestie, welcome to hinic_hwdev_cb_register — the function that literally registers a callback handler for MGMT events. that's the whole vibe. the way this is a void function that just quietly does its thing and returns nothing? iconic. no return value, no drama, periodt. 💖

---

✨ SYNOPSIS ✨

void hinic_hwdev_cb_register (struct hinic_hwdev *hwdev , enum
hinic_mgmt_msg_cmd cmd , void *handle , void (*handler)(void *handle,
void *buf_in, u16 in_size, void *buf_out, u16 *out_size) );

like, yes, that signature is a whole mouthful but we stan a thorough function signature 🫶

---

🌸 ARGUMENTS 🌸

• hwdev — the NIC HW device. your main character hardware, fr fr 👑
• cmd — the mgmt event. this is the thing you're signing up for, iykyk 💅
• handle — private data for the handler. your little stash of context that gets passed along 🎀
• handler — event handler. the actual callback that runs when the event pops off 🔥

ngl there's nothing dangerous here, but if you register a handler you should probably also know about hinic_hwdev_cb_unregister(9) — just saying 🙈

and that's a wrap, babe! this page dropped from ./drivers/net/ethernet/huawei/... back in October 2026, and it's still serving hinic_hwdev_cb_register(9) realness. go forth and register those callbacks 💜🌈⭐
