idpf_is_rdma_cap_ena(9)

💖 idpf_is_rdma_cap_ena(9) — the Kernel API Manual bestie edition 💖

okay so you're deep in the idpf driver (that's the Intel Ethernet one, iykyk) and you need to know one tiny thing: is RDMA even a thing here? bestie, this function is literally the vibe check for that. it's giving "one job, does it well" 🎀 — the whole page lives in the Kernel API Manual, and we're gonna walk through it together, no cap.

---

✨ NAME ✨

idpf_is_rdma_cap_ena — determine if RDMA is supported 💅

like, that's it. that's the function. she checks, she tells you, she leaves. icon behavior.

---

🌸 SYNOPSIS 🌸

bool idpf_is_rdma_cap_ena (struct idpf_adapter *adapter );

look at her. one argument, returns a bool. clean, minimal, main character energy fr fr.

---

🦋 ARGUMENTS 🦋

• adapter — the private data struct 💖 that's it, that's the whole description. she just wants her struct idpf_adapter * and she's happy. hand her the adapter and let her cook.

---

⭐ RETURN ⭐

• true — RDMA capability is enabled ✨ slay, go off, RDMA is on
• false — otherwise 💀 no RDMA for you, but it's fine, we're fine, everything's fine

no exit statuses, no signals, no error codes to memorize — just a good old fashioned yes/no. the way that a bool return is lowkey the most peaceful thing in kernel land 🫶

real talk though: don't assume anything beyond what's written here. true = RDMA capability enabled, false = otherwise. periodt. 🙈

like... 42 cross-references. she said "you want lore? I'll give you LORE." 🔥 obsessed, honestly. also note the cute mix of struct and enum prefixes — copy them exactly when you go looking, bestie, the man page girlies don't play about their (9) suffixes 💅

and that's the whole page! source lives at ./drivers/net/ethernet/intel/idpf, dated October 2026 🍓, and yes she's still repping the Kernel API Manual — the idpf_is_rdma_cap_ena(9) girlies stay winning. go check your capability flag and have the day you deserve 💜✨
