ethtool_rxf...r_can_resize(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ethtool_rxfh_indir_can_resize ✨

okay so bestie, welcome to the Kernel API Manual 🎀 — this one's a little function with a big job and honestly? she ate.

🌸 NAME 🌸

ethtool_rxfh_indir_can_resize — the vibe check that tells you whether context 0's indir table is allowed to resize 💖

✨ SYNOPSIS ✨

bool ethtool_rxfh_indir_can_resize(struct net_device *dev, const u32 *tbl,
                                   u32 old_size, u32 new_size);

🦋 ARGUMENTS 🦋

  • dev — the network device, obviously. main character energy 🫶
  • tbl — the indirection table itself, living its life
  • old_size — how many entries the table has right now
  • new_size — how many entries it wants to have, slay

🌼 DESCRIPTION 🌼

So here's the tea ☕: this function validates that tbl can be resized from old_size to new_size without data loss. Literally just checking, no cap.

It uses the user_size floor from context 0. And when user_size is zero? That means the table isn't user-configured, so the resize always succeeds — iconic behaviour tbh. ✨

Also super important: it's read-only. It does not modify the table. Not even a little. Not even a smidge. 🙈

🔥 RETURN 🔥

  • true — yup, the resize is possible, go off 👑
  • false — nope, not today 💀
