rtl83xx_port_mdb_del(9)

📦 version 7.3.1, in nixpkgs unstable

💅 rtl83xx_port_mdb_del — NAME ✨

okay so bestie, welcome to rtl83xx_port_mdb_del — it's a kernel API manual page (section 9, the big kid section, iykyk) and it's literally the function that deletes a multicast database entry from a port database. that's the whole vibe. gone. bye. 🫶

🦋 SYNOPSIS 🦋

int rtl83xx_port_mdb_del (struct dsa_switch *ds , int port , const
       struct switchdev_obj_port_mdb *mdb , struct dsa_db db );

no cap, that's the exact signature — she takes four things and hands you back an int. copy it character for character or she WILL be mad at you 💀

🎀 ARGUMENTS 🎀

  • ds — the DSA switch instance. your main character switch, basically 👑
  • port — the port index. which port we're doing this to, be specific ✨
  • mdb — the multicast database entry you wanna delete. the const struct switchdev_obj_port_mdb *, obvs 🙈
  • db — the database where the entry should be removed. struct dsa_db, that's the one 🍓

🌸 DESCRIPTION 🌸

so what she actually does: this function deletes a multicast database entry — and it'll do it from either the standalone port database or from a bridge database. literally either one, she's flexible like that 💅✨

💜 CONTEXT 💜

Can sleep. 😴

that's it. that's the whole section. she can sleep, so act accordingly (iykyk — don't call her from an atomic context, bestie, that's giving chaos 😭).

🔥 RETURN 🔥

  • 0 — success, slay, we ate 💖
  • negative value — failure, and not the cute kind 😭
