ENUM EF4_FILTER_MATCH_FLAGS(9)

🦋 NAME 🦋

enum ef4_filter_match_flags — Flags for hardware filter match type ✨

Okay bestie, this is the Kernel API Manual page for enum ef4_filter_match_flags, and it's literally the vibe check for hardware filter match types. No cap. 💅

🌈 SYNOPSIS 🌈

enum ef4_filter_match_flags {
    EF4_FILTER_MATCH_REM_HOST ,
    EF4_FILTER_MATCH_LOC_HOST ,
    EF4_FILTER_MATCH_REM_MAC ,
    EF4_FILTER_MATCH_REM_PORT ,
    EF4_FILTER_MATCH_LOC_MAC ,
    EF4_FILTER_MATCH_LOC_PORT ,
    EF4_FILTER_MATCH_ETHER_TYPE ,
    EF4_FILTER_MATCH_INNER_VID ,
    EF4_FILTER_MATCH_OUTER_VID ,
    EF4_FILTER_MATCH_IP_PROTO ,
    EF4_FILTER_MATCH_LOC_MAC_IG

};

💖 Constants 💖

• EF4_FILTER_MATCH_REM_HOST — match on the remote IP host address 🌐
• EF4_FILTER_MATCH_LOC_HOST — match on the local IP host address 🏠
• EF4_FILTER_MATCH_REM_MAC — match on the remote MAC address 🧬
• EF4_FILTER_MATCH_REM_PORT — match on the remote TCP/UDP port 🔌
• EF4_FILTER_MATCH_LOC_MAC — match on the local MAC address 🏡
• EF4_FILTER_MATCH_LOC_PORT — match on the local TCP/UDP port 🔌
• EF4_FILTER_MATCH_ETHER_TYPE — match on the Ether-type 🏷️
• EF4_FILTER_MATCH_INNER_VID — match on the inner VLAN ID 🎀
• EF4_FILTER_MATCH_OUTER_VID — match on the outer VLAN ID 🎀
• EF4_FILTER_MATCH_IP_PROTO — match on the IP transport protocol 🚚
• EF4_FILTER_MATCH_LOC_MAC_IG — match on the local MAC address I/G bit. It's used for RX default unicast and multicast/broadcast filters. 👑

🌸 Description 🌸

So here's the tea: only some combinations are supported, depending on NIC type. 👀

• Falcon supports RX filters matching by {TCP,UDP}/IPv4 4-tuple or local 2-tuple (only implemented for Falcon B0) 🦅
• Siena supports RX and TX filters matching by {TCP,UDP}/IPv4 4-tuple or local 2-tuple, or local MAC with or without outer VID, and RX default filters 🌸
• Huntington supports filter matching controlled by firmware, potentially using {TCP,UDP}/IPv{4,6} 4-tuple or local 2-tuple, local MAC or I/G bit, with or without outer and inner VID 👑
