💅 rte_table_action_encap_config

okay so bestie, welcome to the glow-up of rte_table_action_encap_config — your new fave struct, from the rte_table_...ncap_config(3) page in the Library Functions Manual. it's giving "encap action configuration, but make it fashion" and honestly? she ate. 🎀

✨ NAME ✨

rte_table_action_encap_config — the struct that holds all your packet-encapsulation settings, per table action profile. no cap. 💖

---

✨ SYNOPSIS ✨

#include <rte_table_action.h>

🦋 Data Fields

uint64_t encap_mask
union {
   struct {
      uint32_t data_offset
      int vlan
      int ip_version
   } vxlan
};

---

✨ Detailed Description ✨

it's the encap action configuration (per table action profile, iykyk). that's the whole vibe.

✨ Field Documentation ✨

🧚 uint64_t encap_mask

the bit mask that defines the whole set of packet encapsulations enabled for the current table action profile. here's the tea ☕: if bit (1 << N) is set in encap_mask, then packet encapsulation N is enabled — and if it's not set, it's disabled. periodt.

🌸 uint32_t data_offset

this is your input packet to be encapsulated ✨ — specifically, the offset within the input packet buffer to the start of the Ethernet frame to be encapsulated. and heads up, bestie: offset 0 points to the first byte of the MBUF structure. yes, literally byte zero. don't forget it. 😭

📍 Definition at line 517 of file rte_table_action.h.

🦋 int vlan

encapsulation header behaviour check 🎀: non-zero when the encapsulation header includes a VLAN tag, zero otherwise. simple as that, fr fr.

📍 Definition at line 522 of file rte_table_action.h.

🌈 int ip_version

the IP version of the IP header within the encapsulation header. and the mapping is kinda iconic in how it flips what you'd expect: non-zero for IPv4, zero for IPv6. yes for real. write it down. 💀

📍 Definition at line 528 of file rte_table_action.h.

💜 struct { ... } vxlan

VXLAN-specific configuration. she's a struct, she's nested, she's slaying. 👑

⭐ union { ... }

encapsulation type specific configuration — i.e. the union where each encapsulation type gets to have its own lil moment. ✨
