STRUCT L3MDEV_OPS(9)

💜 struct l3mdev_ops(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, poking at L3 master devices, and you need to know what knobs a driver can hook into. that's literally this whole page. it's the ops struct for l3mdev — the l3mdev operations, periodt. 🎀

✨ NAME ✨

struct l3mdev_ops — l3mdev operations. that's it, that's the vibe. 🦋

🌸 SYNOPSIS 🌸

here's the whole shape of it, copy it exactly, no cap:

struct l3mdev_ops {
    u32 (*l3mdev_fib_table)(const struct net_device *dev);
    struct sk_buff * (*l3mdev_l3_rcv)(struct net_device *dev, struct
sk_buff *skb, u16 proto);
    struct sk_buff * (*l3mdev_l3_out)(struct net_device *dev, struct
sock *sk, struct sk_buff *skb, u16 proto);
    struct dst_entry * (*l3mdev_link_scope_lookup)(const struct
net_device *dev, struct flowi6 *fl6);
 };

like… four function pointers, all gorgeous, all doing their own little job. main character energy from every single one. 💅

👑 Members 👑

• l3mdev_fib_table — hands you the FIB table id to use for lookups. it's giving "which table are we even using" energy. 🔥
• l3mdev_l3_rcv — the hook that plugs into the L3 receive path. incoming packets, we see you. 🙈
• l3mdev_l3_out — the hook that plugs into the L3 output path. bye bestie, off you go. ✨
• l3mdev_link_scope_lookup — the IPv6 lookup for linklocal and mcast destinations. lowkey the most niche one and honestly? iconic. 💀

and that's the page, bestie! 🫶 this little masterpiece is from ./include/net, dated October 2026, and it's filed under struct l3mdev_ops(9) — go forth and hook those ops, you're gonna slay. 🌈⭐💖
