STRUCT NFP_ETH_TABLE(9)

💖 NAME 💖

struct nfp_eth_table — the ETH table info, bestie. That's it, that's the whole vibe ✨

---

🌸 SYNOPSIS 🌸

okay so picture it: a big table, and inside it, more tables. it's giving nested-struct main character energy 👑

struct nfp_eth_table {
    unsigned int count;
    unsigned int max_index;
    struct nfp_eth_table_port {
      unsigned int eth_index;
      unsigned int index;
      unsigned int nbi;
      unsigned int base;
      unsigned int lanes;
      unsigned int speed;
      unsigned int interface;
      enum nfp_eth_media media;
      enum nfp_eth_fec fec;
      enum nfp_eth_fec act_fec;
      enum nfp_eth_aneg aneg;
      u8 mac_addr[ETH_ALEN];
      u8 label_port;
      u8 label_subport;
      bool enabled;
      bool tx_enabled;
      bool rx_enabled;
      bool supp_aneg;
      bool rx_pause;
      bool tx_pause;
      bool override_changed;
      u8 port_type;
      unsigned int port_lanes;
      bool is_split;
      unsigned int fec_modes_supported;
      u64 link_modes_supp[2];
      u64 link_modes_ad[2];
    } ports[];
};

like, that's the whole thing. the ports[] flex array at the end? iconic. it's literally the main event 💅

🦋 Members 🦋

okay bestie, field-by-field, let's go — and yes you have to read all of them, no skipping 🙈

• count — the number of table entries. how many we got.
• max_index — the max of the index fields across all ports. the biggest index in the room, lowkey.
• ports — the table of ports. the actual lineup, periodt.

and now the port fields, one by one:

• ports.eth_index — port index according to legacy ethX numbering. retro vibes fr.
• ports.index — chip-wide first channel index.
• ports.nbi — NBI index.
• ports.base — first channel index (within NBI).
• ports.lanes — number of channels.
• ports.speed — interface speed (in Mbps).
• ports.interface — the interface (module) plugged in.
• ports.media — media type of the interface.
• ports.fec — forward error correction mode.
• ports.act_fec — active forward error correction mode. (the one actually doing something ✨)
• ports.aneg — auto negotiation mode.
• ports.mac_addr — interface MAC address.
• ports.label_port — port id.
• ports.label_subport — id of interface within port (for split ports).
• ports.enabled — is enabled? 👀
• ports.tx_enabled — is TX enabled?
• ports.rx_enabled — is RX enabled?
• ports.rx_pause — Switch of RX pause frame.
• ports.tx_pause — Switch of Tx pause frame.
• ports.override_changed — is media reconfig pending? like, are we waiting on a glow-up 💅
• ports.port_type — one of PORT_* defines for ethtool.
• ports.port_lanes — total number of lanes on the port (sum of lanes of all subports). math queen 🧮
• ports.is_split — is interface part of a split port.
• ports.fec_modes_supported — bitmap of FEC modes supported.
• ports.link_modes_supp — bitmap of link modes supported.
• ports.link_modes_ad — bitmap of link modes advertised.

ngl, supp_aneg is chillin' in the struct up there but it's not in the Members list — that's just how the page is, don't come for me 🫶

okay that's the whole page, bestie — Kernel API Manual realness, straight from ./drivers/net/ethernet/netrono... (yes it's truncated, that's the source line as given, don't @ me 😭) dated October 2026. mwah, slay, go forth and read your structs 💜🌈⭐
