mlx5hws_tabl...default_miss(9)

💅 mlx5hws_tabl...default_miss(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for mlx5hws_tabl...default_miss(9) — yes that's the abbreviated name up in the corner, she's long, she's gorgeous, we move. this is the page where we set up your whole "what happens when nothing matches" situation, and honestly it's giving main character energy 🎀

---

✨ NAME ✨

mlx5hws_table_set_default_miss — sets the default miss table for a mlx5hws_table by using another mlx5hws_table. like, no cap: any traffic that all the table matchers miss gets forwarded straight to the miss table. it's the fallback bestie, the "if nobody claims you, go here" plan 💖

---

🦋 SYNOPSIS 🦋

int mlx5hws_table_set_default_miss (struct mlx5hws_table *tbl , struct
mlx5hws_table *miss_tbl );

literally that's the whole call. two pointers, one int coming back. slay ✨

---

🌸 ARGUMENTS 🌸

• tbl — the source table, a.k.a. the one you're configuring. she's the one getting the new miss behaviour 🫶
• miss_tbl — the target (miss) table 💅 or, plot twist, pass NULL to remove the current miss table. yes, NULL is the "never mind, undo it" option, iconic.

---

💀 RETURN 💀

• zero on success 🎉
• non zero otherwise 😭 (so like, vibe check your return value, fr fr)

no lying: the page says "zero on success non zero otherwise" and that's the whole deal — don't invent extra error codes, i'm not gonna gaslight you like that 🙈
