STRUCT VPORT_OPS(9)

🦋 struct vport_ops(9) 🦋

hey bestie, welcome to the Kernel API Manual — this is the struct vport_ops(9) page, and it is literally the definition of a type of virtual port. main character struct energy, no cap. 💅

💖 NAME 💖

struct vport_ops — definition of a type of virtual port. periodt.

✨ SYNOPSIS ✨

okay so here is the whole struct, exactly as it is, bestie:

struct vport_ops {
    enum ovs_vport_type type;
    struct vport *(*create)(const struct vport_parms *);
    void (*destroy)(struct vport *);
    int (*send)(struct sk_buff *skb);
    struct list_head list;
};

• type — the OVS_VPORT_TYPE_* value for this type of virtual port. it's giving "which flavor of vport are we today" ✨
• create — create a new vport configured as specified. on success it returns a new vport allocated with ovs_vport_alloc; otherwise it returns an ERR_PTR value. iconic behavior, honestly. 💖
• destroy — destroys a vport. it must call vport_free on the vport, but not before an RCU grace period has elapsed. this is the serious part, bestie — do not skip the grace period. 😭
• send — send a packet on the device. zero for dropped packets or negative for error. that's the whole mood. 🔥
• list — list entry in the global list of vport types. it's in the group chat now. 👑
