STRUCT RIO_SWITCH_OPS(9)

✨ struct rio_switch_ops(9) ✨

okay so bestie, this is a page from the Linux Kernel API Manual, and honestly? it's giving "backstage pass to the RIO switch world" 🎀 lowkey iconic.

🌸 NAME 🌸

struct rio_switch_ops — the per-switch operations, fr fr. like every switch gets its own little toolbox of moves 💅

---

🦋 SYNOPSIS 🦋

struct rio_switch_ops {
    struct module *owner;
    int (*add_entry) (struct rio_mport *mport, u16 destid, u8 hopcount,
u16 table, u16 route_destid, u8 route_port);
    int (*get_entry) (struct rio_mport *mport, u16 destid, u8 hopcount,
u16 table, u16 route_destid, u8 *route_port);
    int (*clr_table) (struct rio_mport *mport, u16 destid, u8 hopcount,
u16 table);
    int (*set_domain) (struct rio_mport *mport, u16 destid, u8 hopcount,
u8 sw_domain);
    int (*get_domain) (struct rio_mport *mport, u16 destid, u8 hopcount,
u8 *sw_domain);
    int (*em_init) (struct rio_dev *dev);
    int (*em_handle) (struct rio_dev *dev, u8 swport);
 };

like, look at all those function pointers bestie 😭 it's a whole vibe check for whoever's implementing a switch 💜

🌈 Members 🌈

• owner — the module owner of this structure. literally who's holding the keys to this thing 👑
• add_entry — callback for the switch-specific route add function. it's the "add a route" girly ✨
• get_entry — callback for the switch-specific route get function. she fetches the route for you 🫶
• clr_table — callback for the switch-specific clear route table function. wiping the slate clean, periodt 💅
• set_domain — callback for the switch-specific domain setting function. setting that domain, no cap 🎀
• get_domain — callback for the switch-specific domain get function. reading the domain back out, slay 🌸
• em_init — callback for the switch-specific error management init function. error management setup time 🧚
• em_handle — callback for the switch-specific error management handler function. she handles the errors, highkey main character energy 🔥

⭐ Description ⭐

So basically, this struct defines all the operations you need to initialize and control a particular RIO switch device 💖 it's the blueprint, the whole playbook, iykyk.
