STRUCT ETHTOOL_RXFH_FIELDS(9)

💅 struct ethtool_rxfh_fields(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this is the page for struct ethtool_rxfh_fields, and it’s literally the Rx Flow Hashing (RXFH) header field config. no cap, it’s a little struct with big “which header fields are we hashing” energy 🫶

🌸 NAME 🌸

struct ethtool_rxfh_fields — Rx Flow Hashing (RXFH) header field config. periodt 💖

✨ SYNOPSIS ✨

here’s the struct in all its iconic glory:

struct ethtool_rxfh_fields {
    u32 data;
    u32 flow_type;
    u32 rss_context;
 };

🫶 Members 🫶

three members, one vibe check, let’s go:

• data (u32) — which header fields are used for hashing, aka a bitmask of RXH_* defines. it’s giving “pick your hash fields” 💅
• flow_type (u32) — the L2-L4 network traffic flow type. yes bestie, layer 2 through layer 4, the whole flow-type moment 🌈
• rss_context (u32) — RSS context, and it will only be used if rxfh_per_ctx_fields is set in struct ethtool_ops. lowkey conditional queen 👑
