i40e_rx_is_...mming_status(9)

💅 i40e_rx_is_programming_status 💅

okay so real talk, bestie — this is a page straight out of the Kernel API Manual, and the function's full name is i40e_rx_is_programming_status (the header just truncates it because terminals are dramatic 😭). It's a tiny little helper with one job, and it slays at that job.

✨ NAME ✨

i40e_rx_is_programming_status — the vibe check for "is this a programming status descriptor?" 🎀

🦋 SYNOPSIS 🦋

bool i40e_rx_is_programming_status (u64 qword1 );

🍓 ARGUMENTS 🍓

• qword1 — this is the qword1 that represents status_error_len in CPU ordering. That's it, that's the whole argument, ngl she's low maintenance 💅

👑 DESCRIPTION 👑

So here's the tea ☕ — the value sitting in the descriptor length field is what tells you whether this thing is a programming status descriptor for flow director or FCoE, and it signals that by being the value of I40E_RX_PROG_STATUS_DESC_LENGTH. If it's not that value? Then it's just a packet descriptor, bestie. A regular degular packet. No cap. 🌸

Like, one field, one constant, one absolutely iconic little decision tree. The way that a length field can tell you so much about a descriptor's whole personality?? Obsessed. 💖

💀 tiny reminder: this whole thing lives in the i40e driver world, so if you're poking at Intel ethernet RX descriptor code, you're in exactly the right place. If you're not — why are you here, girl, go touch grass 🧚

and that's a wrap, bestie!! 🎀 this iconic little page came to you courtesy of ./drivers/net/ethernet/intel/i40e, dated October 2026 — mwah, love u, go read your descriptors 💜✨
