STRUCT DPSW_ACL_FIELDS(9)

💅 struct dpsw_acl_fields(9)

okay so bestie, welcome to the Kernel API Manual — yes, the whole thing, and today's main character is struct dpsw_acl_fields, aka the ACL fields, aka the literal blueprint of everything an Access Control List can look at when it's deciding whether your packet is iconic or should be dropped 💀

---

✨ NAME ✨

struct dpsw_acl_fields — ACL fields. That's it, that's the whole vibe. It's a struct of fields. For ACLs. Periodt 🎀

---

🌸 SYNOPSIS 🌸

here's the whole thing, character for character, no cap:

struct dpsw_acl_fields {
    u8 l2_dest_mac[6];
    u8 l2_source_mac[6];
    u16 l2_tpid;
    u8 l2_pcp_dei;
    u16 l2_vlan_id;
    u16 l2_ether_type;
    u8 l3_dscp;
    u8 l3_protocol;
    u32 l3_source_ip;
    u32 l3_dest_ip;
    u16 l4_source_port;
    u16 l4_dest_port;
 };

look at her. twelve fields. organized. layered. lowkey a work of art 🖼️

🦋 MEMBERS 🦋

okk let's go field by field, and yes i'm gonna explain every single one because i want you to actually get it:

• l2_dest_mac — the Destination MAC address 👀 and bestie it covers a LOT of cases: BPDU, Multicast, Broadcast, Unicast, slow protocols, MVRP, STP. it's giving "i contain multitudes."
• l2_source_mac — the Source MAC address. the origin story. where the packet came from 🫶
• l2_tpid — Layer 2 (Ethernet) protocol type, and it's used to identify the following protocols: MPLS, PTP, PFC, ARP, Jumbo frames, LLDP, IEEE802.1ae, Q-in-Q, IPv4, IPv6, PPPoE. eleven whole protocols. she's busy 💅
• l2_pcp_dei — indicates which protocol is encapsulated in the payload 🔥
• l2_vlan_id — layer 2 VLAN ID. the little tag that says which vlan you belong to 🏷️
• l2_ether_type — layer 2 Ethernet type ✨
• l3_dscp — Layer 3 differentiated services code point. fancy networking words, still just a field 😌
• l3_protocol — tells the Network layer at the destination host to which Protocol this packet belongs to. and the following protocol are supported: ICMP, IGMP, IPv4 (encapsulation), TCP, IPv6 (encapsulation), GRE, PTP. that's the whole roster fr fr 📋
• l3_source_ip — Source IPv4 IP 🌈
• l3_dest_ip — Destination IPv4 IP ⭐
• l4_source_port — Source TCP/UDP Port 🍓
• l4_dest_port — Destination TCP/UDP Port 💜
