ice_devlink...w_check_attr(9)

💅 NAME 💅

ice_devlink_port_new_check_attr — bestie, this is the vibe check for new port attributes ✨

So like, this is a page from the Kernel API Manual (ice_devlink...w_check_attr(9)), and it's literally just here to make sure the new port attrs are valid before anything else happens.

---

🎀 SYNOPSIS 🎀

int ice_devlink_port_new_check_attr (struct ice_pf *pf , const struct
devlink_port_new_attrs *new_attr , struct netlink_ext_ack *extack );

---

🌸 ARGUMENTS 🌸

• pf — pointer to the PF structure, aka the main character of this whole function 🫶
• new_attr — the attributes for the new port, like the little outfit the port is gonna wear ✨
• extack — extack for reporting error messages, so when something's off it can actually tell you why 😭

---

🦋 DESCRIPTION 🦋

Okay so real talk: this function checks that the attributes for the new port are valid before continuing on to allocate the devlink port. Like a bouncer at the club checking IDs, but for port attrs 💅 No valid attrs, no port, periodt.

---

⭐ RETURN ⭐

zero on success or an error code on failure. Slay if it's zero, not slay if it's an error code 😭
