ENUM MXL862XX_SS_SP_TAG_RX_PEN(9)

💅 enum mxl862xx_ss_sp_tag_rx_pen (9) — from the Kernel API Manual, bestie ✨

okay so this is a page straight out of the Kernel API Manual, and it's literally all about one little enum that decides what goes into the RX special tag over the preamble 🎀 no cap, that's the whole vibe.

---

🌸 NAME 🌸

enum mxl862xx_ss_sp_tag_rx_pen — RX special tag info over preamble. that's it, that's the queen 👑

---

✨ SYNOPSIS ✨

enum mxl862xx_ss_sp_tag_rx_pen {
    MXL862XX_SS_SP_TAG_RX_PEN_ALL_0 ,
    MXL862XX_SS_SP_TAG_RX_PEN_BYTE_5_IS_16 ,
    MXL862XX_SS_SP_TAG_RX_PEN_BYTE_5_FROM_PREAMBLE ,
    MXL862XX_SS_SP_TAG_RX_PEN_BYTE_2_TO_7_FROM_PREAMBLE

};

like, four whole constants, and every single one is iconic in its own way 🫶

🦋 Constants 🦋

• MXL862XX_SS_SP_TAG_RX_PEN_ALL_0 — the special tag info that gets inserted from byte 2 to 7 is all 0. yep, all of it. zeroes. slay 💀
• MXL862XX_SS_SP_TAG_RX_PEN_BYTE_5_IS_16 — special tag byte 5 is 16, and the other bytes from 2 to 7 are 0. byte 5 said "main character energy" and the rest said "we're background dancers" 😭
• MXL862XX_SS_SP_TAG_RX_PEN_BYTE_5_FROM_PREAMBLE — special tag byte 5 comes from the preamble field, and the others are 0. so byte 5 is literally pulling its content from the preamble, iykyk 🌈
• MXL862XX_SS_SP_TAG_RX_PEN_BYTE_2_TO_7_FROM_PREAMBLE — special tag byte 2 to 7 are all from the preamble field. the whole squad got invited, periodt 🔥
