💅 rte_flow_action_set_dscp

okay bestie, welcome to the rte_flow_action_set_dscp page — it lives in section 3 of the Library Functions Manual, aka the part of the docs where we talk about C functions and not, like, commands you type. no cap.

✨ NAME ✨

rte_flow_action_set_dscp — that's it, that's the whole name. short. iconic. periodt 💖

🌸 SYNOPSIS 🌸

#include <rte_flow.h>

that's literally the only include you need, bestie. go off 🦋

🎀 Detailed Description 🎀

so RTE_FLOW_ACTION_TYPE_SET_IPV4_DSCP and RTE_FLOW_ACTION_TYPE_SET_IPV6_DSCP are the two actions in question — one for the IPv4 header, one for the IPv6 header, because obviously they couldn't just share one single action, we love diversity 💀

what they do: they set the DSCP value for the IPv4/IPv6 header. that's the vibe check. 👑

and here's the detail you absolutely cannot fumble: the DSCP lives in the low 6 bits, and the rest is ignored. like, literally ignored. don't come for those other bits, they are not the moment. 🙈

lowkey important: low 6 bits = DSCP. everything else = not DSCP. the way that the rest is just... ignored. chef's kiss. 🫶

📍 fyi, this whole thing is defined at line 3927 of the file rte_flow.h — so if you ever need to go stare at the source directly (main character behavior, honestly), you know exactly where to look. ⭐
