STRUCT MV_CESA_CAPS(9)

🎀 NAME 🎀

okay so we're looking at struct mv_cesa_caps(9) today, bestie — and yes, that's the one straight out of the Kernel API Manual. it's literally the CESA device capabilities struct, and it's here to spill the tea about what a device can do. periodt. 💅

---

✨ SYNOPSIS ✨

here's the whole shape of it, exactly as she lives in the source — don't touch the spacing, she's sensitive:

       struct mv_cesa_caps {
           int nengines;
           bool has_tdma;
           struct skcipher_alg **cipher_algs;
           int ncipher_algs;
           struct ahash_alg **ahash_algs;
           int nahash_algs;
        };

---

💖 Members 💖

• has_tdma — whether this device has a TDMA block. cute little yes/no situation.
• cipher_algs — supported cipher algorithms.
• ncipher_algs — number of supported cipher algorithms. the count, the receipts, the tally. ✨
• ahash_algs — supported hash algorithms.
• nahash_algs — number of supported hash algorithms. again with the receipts. 🧾

---

🌈 Description 🌈

this structure is used to describe CESA device capabilities. that's the whole assignment. it's giving "capability manifest" and honestly it ate. no cap. 🔥

bestie, this is a kernel struct — it's C, so respect the indentation and don't go renaming fields, iykyk. 🫶
