STRUCT EFX_ASYNC_FILTER_INSERTION(9)

💅 struct efx_async_filter_insertion(9) 💅

okay so bestie, we're in the Kernel API Manual today and this page is literally about struct efx_async_filter_insertion — the whole vibe is "a request to asynchronously insert a filter." That's it, that's the energy. 🦋

✨ NAME ✨

struct efx_async_filter_insertion — the literal Request to asynchronously insert a filter. no cap, that's the entire job description. 🎀

---

🌸 SYNOPSIS 🌸

struct efx_async_filter_insertion {
    struct net_device *net_dev;
    netdevice_tracker net_dev_tracker;
    struct efx_filter_spec spec;
    struct work_struct work;
    u16 rxq_index;
    u32 flow_id;
 };

look at her. six fields. absolutely iconic. 👑

💖 Members 💖

okay so member by member, group-chat style:

• net_dev — a Reference to the netdevice. your girl needs to know which device she's talking about, obviously. 🫶
• net_dev_tracker — the reference tracker entry for net_dev. it's giving "keeping receipts" energy. tracking the reference so nothing gets lost. 💅
• spec — The filter to insert. this is literally the whole point of the request, the main character. ⭐
• work — Workitem for this request. yes she has a work item, she's booked and busy (asynchronously, of course). 🔥
• rxq_index — Identifies the channel for which this request was made. so we know exactly which channel we're doing this for. iykyk. 🌈
• flow_id — Identifies the kernel-side flow for which this request was made. the kernel-side flow, specifically. not to be confused with anything else. ngl the naming here is pretty self-explanatory and we love that for us. 🍓
