STRUCT WWAN_OPS(9)

💅 struct wwan_ops(9) — the Kernel API Manual, but make it fashion

okay bestie, so this page is literally all about struct wwan_ops — the WWAN device ops 🦋. yes, ops as in operations, as in the little function-pointer squad that tells the kernel how to handle your WWAN netdev. it's giving "backstage pass to the whole device lifecycle" and honestly we're obsessed ✨

🌸 SYNOPSIS 🌸

here's the whole struct, copied exactly, no cap, don't come for me:

struct wwan_ops {
    unsigned int priv_size;
    void (*setup)(struct net_device *dev);
    int (*newlink)(void *ctxt, struct net_device *dev, u32 if_id, struct
netlink_ext_ack *extack);
    void (*dellink)(void *ctxt, struct net_device *dev, struct list_head
*head);
 };

like… four members. short and iconic. main character energy fr fr 💜

🎀 Members 🎀

• priv_size — the size of the private netdev data area 💖. yes it's just a number, yes it matters, it's how much room your private stuff gets to live in.
• setup — set up a new netdev ✨. this is where the new netdev gets its lil makeover.
• newlink — register the new netdev 🫶. takes void *ctxt, struct net_device *dev, u32 if_id, and a struct netlink_ext_ack *extack. it's the "welcome to the family" moment.
• dellink — remove the given netdev 💀. takes void *ctxt, struct net_device *dev, and a struct list_head *head. sad but necessary, we don't gatekeep deletions here.

anyway, that's the whole vibe — this came out of ./include/linux and it's dated October 2026, so mark your calendars bestie 🗓️💖. slay, stay hydrated, and remember: the kernel loves you. periodt. 🎀✨
