📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

We're in the Kernel API Manual, bestie, and this page is enum (anonymous)(9). It covers the &libeth_xdp_tx_frame and &libeth_xdp_tx_desc flags. Periodt.

✨ SYNOPSIS ✨

enum (anonymous) {
    LIBETH_XDP_TX_LEN ,
    LIBETH_XDP_TX_CSUM ,
    LIBETH_XDP_TX_XSKMD ,
    LIBETH_XDP_TX_FIRST ,
    LIBETH_XDP_TX_LAST ,
    LIBETH_XDP_TX_MULTI ,
    LIBETH_XDP_TX_FLAGS

};

🎀 Constants 🎀

Okay so these are the flag constants inside the enum, and every single one is doing its little thing:

  • LIBETH_XDP_TX_LEN — only for XDP_TX, [15:0] of ::len_fl is actual length
  • LIBETH_XDP_TX_CSUM — for XSk xmit, enable checksum offload
  • LIBETH_XDP_TX_XSKMD — for XSk xmit, mask of the metadata bits
  • LIBETH_XDP_TX_FIRST — indicates the frag is the first one of the frame
  • LIBETH_XDP_TX_LAST — whether the frag is the last one of the frame
  • LIBETH_XDP_TX_MULTI — whether the frame contains several frags
  • LIBETH_XDP_TX_FLAGS — only for XDP_TX, [31:16] of ::len_fl is flags
