rte_flow_item_vlan(3) — the VLAN item that ate 💅

okay so this page is from the Library Functions Manual, and the main character is rte_flow_item_vlan(3). It’s literally the flow item for matching an 802.1Q/ad VLAN tag, and lowkey, every detail is here.

🌸 NAME 🌸

rte_flow_item_vlan — that’s the name, slay. 💖

🎀 SYNOPSIS 🎀

#include <rte_flow.h>

✨ Data Fields ✨

  • uint32_t has_more_vlan:1
  • uint32_t reserved:31

💖 Detailed Description 💖

okay so RTE_FLOW_ITEM_TYPE_VLAN matches an 802.1Q/ad VLAN tag — it’s giving iconic tagged-packet realness. The corresponding standard outer EtherType (TPID) values are RTE_ETHER_TYPE_VLAN or RTE_ETHER_TYPE_QINQ. It can be overridden by the preceding pattern item. no cap.

If a VLAN item is present in the pattern, then only tagged packets will match the pattern. The field has_more_vlan can be used to match any type of tagged packets, instead of using the eth_proto field of hdr. If the eth_proto of hdr and has_more_vlan fields are not specified, then any tagged packets will match the pattern. fr fr, that’s the whole rule.
