STRUCT PCH_GBE_TX_DESC(9)

💅 struct pch_gbe_tx_desc(9)

okay bestie, gather round, because we're cracking open the Kernel API Manual (section 9, obviously) and today's main character is struct pch_gbe_tx_desc — the Transmit Descriptor. it's giving "small struct, huge responsibilities." no cap. 🎀

---

✨ NAME ✨

struct pch_gbe_tx_desc — Transmit Descriptor. that's it, that's the vibe. she's a descriptor and she transmits. iconic behaviour fr fr. 💅

---

🦋 SYNOPSIS 🦋

here's the whole glow-up, copied exactly so you don't have to squint at the original:

struct pch_gbe_tx_desc {
    u32 buffer_addr;
    u16 length;
    u16 reserved1;
    u16 tx_words_eob;
    u16 tx_frame_ctrl;
    u8 dma_status;
    u8 reserved2;
    u16 gbec_status;
 };

look at her. fields all lined up, types all matching, a couple of reserved slots doing absolutely nothing but holding space like a true supportive bestie. we stan. 🫶

🌸 Members 🌸

okay so let's meet the cast, one field at a time, and yes i will be giving each one a moment:

• buffer_addr — TX Frame Buffer Address. this is where the frame's buffer lives. the address. of the buffer. for the frame. that's being transmitted. literally the whole point of her existence. 📍
• length — Data buffer length. how long the data buffer is. she's telling you the size, bestie, please respect it. 📏
• reserved1 — Reserved. no thoughts, head empty, do not touch. 🙈
• tx_words_eob — TX word count and Byte position. words and bytes, she contains multitudes. 🔥
• tx_frame_ctrl — TX Frame Control. the control bits for the TX frame. she's in charge. main character energy honestly. 👑
• dma_status — DMA Status. the status. of the DMA. (it's a u8, she's little but she knows things.) ⭐
• reserved2 — Reserved. second reserved slot, also doing nothing, also slaying at it. 💀
• gbec_status — GMAC Status. the GMAC status lives here. that's the whole descriptor, start to finish, no skips. 💖

---

quick vibe check: reserved1 and reserved2 are Reserved. don't write cute little values into them. they are not for you. periodt. 🚫
