✨ NAME ✨

ovs_vport_get_upcall_stats — retrieve upcall stats, no cap 💫

---

🌸 SYNOPSIS 🌸

int ovs_vport_get_upcall_stats (struct vport *vport , struct sk_buff
*skb );

like literally that's the whole signature. it returns an int, it takes two pointers, it's giving "small function, big responsibilities" 😌

🎀 ARGUMENTS 🎀

• vport — the vport you're pulling stats from, aka the main character of this whole operation 👑
• skb — the sk_buff where the upcall stats get appended. it's the little canvas you're painting on, fr fr 🖌️

🦋 DESCRIPTION 🦋

Retrieves upcall stats for the given device. that's it, that's the vibe 💖

⚠️ bestie listen to me: Must be called with ovs_mutex or rcu_read_lock. this is not a suggestion, this is the law. lock it up or things get uncomfy 😭🔒
