ENUM SKB_FRAME_DESC_FLAGS(9)

okay bestie, buckle up — this is enum skb_frame_desc_flags(9) from the Kernel API Manual, and it’s literally the flag cheat sheet for &struct skb_frame_desc. no cap, it’s short but every bit matters 💅

💖 NAME 💖

enum skb_frame_desc_flags — the flags for &struct skb_frame_desc. that’s the whole vibe: these are the little status bits that tell you what’s up with that struct 🎀

✨ SYNOPSIS ✨

enum skb_frame_desc_flags {
    SKBDESC_DMA_MAPPED_RX ,
    SKBDESC_DMA_MAPPED_TX ,
    SKBDESC_IV_STRIPPED ,
    SKBDESC_NOT_MAC80211 ,
    SKBDESC_DESC_IN_SKB

};

🎀 Constants 🎀

• SKBDESC_DMA_MAPPED_RX — the skb_dma field has been mapped for RX. slay, receive-side DMA is mapped 💖
• SKBDESC_DMA_MAPPED_TX — the skb_dma field has been mapped for TX. transmit-side DMA mapped, iconic ✨
• SKBDESC_IV_STRIPPED — the frame contained an IV/EIV provided by mac80211, but it was stripped for processing by the driver. so the driver handled it, bestie 🫶
• SKBDESC_NOT_MAC80211 — the frame didn’t originate from mac80211, so don’t try to pass it back. noted, no take-backsies 😭
• SKBDESC_DESC_IN_SKB — the descriptor is at the start of the skb, instead of in the desc field. it’s giving “descriptor lives up front” energy 👑
