STRUCT ETHTOOL_RX_NTUPLE(9)

💖 struct ethtool_rx_ntuple(9) 💖

okay so welcome to the Kernel API Manual page for struct ethtool_rx_ntuple — it's giving "command to set or clear RX flow filter" energy, and honestly it's lowkey iconic. let's get into it, bestie.

✨ NAME ✨

struct ethtool_rx_ntuple — command to set or clear RX flow filter. literally that's the whole vibe.

🌸 SYNOPSIS 🌸

       struct ethtool_rx_ntuple {
           __u32 cmd;
           struct ethtool_rx_ntuple_flow_spec      fs;
        };

🎀 Members 🎀

• cmd — the command number, and it is ETHTOOL_SRXNTUPLE. that's the one, no cap.
• fs — the flow filter specification. yes, the actual filter details live here.
