STRUCT VIF_DEVICE(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to struct vif_device(9) from the Kernel API Manual 💖 this one is literally the interface representor for multicast routing, and we're gonna get into every single member, no skips, periodt ✨

🌸 NAME 🌸

struct vif_device — interface representor for multicast routing 🦋

✨ SYNOPSIS ✨

struct vif_device {
    struct net_device *dev;
    netdevice_tracker dev_tracker;
    unsigned long bytes_in, bytes_out;
    unsigned long pkt_in, pkt_out;
    unsigned long rate_limit;
    unsigned char threshold;
    unsigned short flags;
    int link;
    struct netdev_phys_item_id dev_parent_id;
    __be32 local, remote;
 };
