STRUCT MII_TIMESTAMPING_CTRL(9)

👑 struct mii_timestamping_ctrl 👑

okay so bestie, welcome to the Kernel API Manual — we're talking about struct mii_timestamping_ctrl today, and it's literally the MII time stamping controller interface. no cap, that's the whole vibe of this page. 💅

✨ NAME ✨

struct mii_timestamping_ctrl — MII time stamping controller interface.

🎀 SYNOPSIS 🎀

struct mii_timestamping_ctrl {
    struct mii_timestamper *(*probe_channel)(struct device *device,
unsigned int port);
    void (*release_channel)(struct device *device, struct
mii_timestamper *mii_ts);
 };

💅 Members 💅

• probe_channel — this is the callback into the controller driver, and its whole job is announcing that the 'port' channel exists. 🫶 the 'device' field? yeah, that one had already been passed to register_mii_tstamp_controller — so it's not new info, it's a hand-me-down. now listen up: the driver must return either a pointer to a valid MII timestamper instance or PTR_ERR. that's not optional, bestie. periodt. 🔥
• release_channel — the cleanup bestie ✨ it releases an instance that you got via .probe_channel. you know the drill: what gets probed, gets released. 🎀
