rte_flow_action_count(3)

💖 rte_flow_action_count 💖

okay bestie, gather round, because today we're getting into rte_flow_action_count, a section 3 library function situation from the DPDK cinematic universe. it's giving "small struct, big responsibilities", and honestly? we're obsessed. 🎀

✨ SYNOPSIS ✨

#include <rte_flow.h>

🌸 Data Fields 🌸

• uint32_t id — yes queen, that's the whole field list, we love a minimal icon 👑

🦋 Detailed Description 🦋

⚠️ Warning — EXPERIMENTAL: this structure may change without prior notice. no cap, it can shift under you like a group chat at 2am, so don't build your whole personality on it 💀

This is the RTE_FLOW_ACTION_TYPE_COUNT vibe. ✨

Basically, it adds a counter action to a matched flow. you match a flow, you count it, slay.

now here's the important part, and it's highkey important: if you've got more than one count action specified in a single flow rule, then each action must specify a unique ID. literally no two counters sharing an ID in the same rule, that's the rule bestie 🙈

and how do you actually get at these counters? you retrieve and reset them through rte_flow_query(), see struct rte_flow_query_count. that's your one-stop shop for reading and zeroing, iykyk 💅

one more thing that's easy to miss (ngl, super easy to miss): for ports within the same switch domain, the counter ID namespace extends to all ports within that switch domain. so it's not per-port isolated, it's shared across the whole domain — whole squad shares the namespace, fr fr 🌈

oh and fun fact, all this lives at Definition at line 3450 of file rte_flow.h. remember that address like it's a crush's birthday 🫶
