ENUM EF4_FILTER_FLAGS(9)

✨ enum ef4_filter_flags(9) ✨ — Kernel API Manual 💅

🌸 NAME 🌸

enum ef4_filter_flags — the flags for hardware filter specifications, bestie 💖

🦋 SYNOPSIS 🦋

okay so here's the whole enum, no cap:

enum ef4_filter_flags {
    EF4_FILTER_FLAG_RX_RSS ,
    EF4_FILTER_FLAG_RX_SCATTER ,
    EF4_FILTER_FLAG_RX_OVER_AUTO ,
    EF4_FILTER_FLAG_RX ,
    EF4_FILTER_FLAG_TX

};

🎀 Constants 🎀

• EF4_FILTER_FLAG_RX_RSS — use RSS to spread across multiple queues, periodt. By default, matching packets will be delivered only to the specified queue. If this flag is set, they will be delivered to a range of queues offset from the specified queue number according to the indirection table. it's giving "share the load" energy ✨
• EF4_FILTER_FLAG_RX_SCATTER — enable DMA scatter on the receiving queue. lowkey a whole vibe for RX 🫶
• EF4_FILTER_FLAG_RX_OVER_AUTO — indicates a filter that is overriding an automatic filter, with priority EF4_FILTER_PRI_AUTO. This may only be set by the filter implementation for each type. A removal request will restore the automatic filter in its place. so like, it's an override situation, and removal puts the automatic filter back 💅
• EF4_FILTER_FLAG_RX — filter is for RX 💖
• EF4_FILTER_FLAG_TX — filter is for TX 💜

bestie, note the caveat on EF4_FILTER_FLAG_RX_OVER_AUTO: it may only be set by the filter implementation for each type, fr fr. don't just be out here setting it yourself 🙈
