idpf_get_max_tx_hdr_size(9)

💅 idpf_get_max_tx_hdr_size(9) — from the Kernel API Manual, bestie

okay so picture this: you're poking around the idpf driver, and you need to know how big a tx header can get. that's it. that's the whole function. tiny, iconic, does exactly one thing — get the size of tx header. no cap. 🎀

✨ NAME ✨

idpf_get_max_tx_hdr_size — get the size of tx header 💖

---

🌸 SYNOPSIS 🌸

u16 idpf_get_max_tx_hdr_size (struct idpf_adapter *adapter );

that's the whole signature, bestie — it hands you back a u16, and it wants exactly one thing from you: the adapter. 🦋

🫶 ARGUMENTS 🫶

• adapter — Driver specific private structure. yeah, it's the good stuff, the driver's own little private stash of info. you gotta pass it in, no skipping. 💅
