ice_fdb_add(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to ice_fdb_add(9) from the Kernel API Manual — the iconic little function that adds an entry to the hardware database. no cap, it's giving kernel API main character energy. 💅✨

🌸 NAME 🌸

ice_fdb_add — add an entry to the hardware database.

✨ SYNOPSIS ✨

here's the signature, character-for-character, because we do not play with kernel API code in this house:

int ice_fdb_add (struct ndmsg *ndm , struct nlattr *tb[] , struct
net_device *dev , const unsigned char *addr , u16 vid , u16 flags , bool
*notified , struct netlink_ext_ack *extack );

🎀 ARGUMENTS 🎀

okay bestie, the argument tea is piping hot — every parameter, no skips:

  • ndm — the input from the stack (struct ndmsg *ndm). literally the stack's little message package. 💌
  • tb — pointer to array of nladdr (unused — iconically just vibing there). the struct nlattr *tb[] slot is lowkey not doing anything here. 🙈
  • dev — the net device pointer (struct net_device *dev). yes ma'am, the netdev itself. 🫶
  • addr — the MAC address entry being added (const unsigned char *addr). the actual MAC address tea. 🍓
  • vid — VLAN ID (u16 vid). periodt. 🎀
  • flags — instructions from stack about fdb operation (u16 flags). the stack said what it said. 💅
  • notified — whether notification was emitted (bool *notified). the emit-or-not receipt. ✨
  • extack — netlink extended ack (struct netlink_ext_ack *extack). the extended-ack bestie. 🦋
