STRUCT TBSTREAM_FRAME(9)

💖 NAME 💖

struct tbstream_frame — Frame submitted to/from the rings

okay so real talk, bestie: this page is straight out of the Kernel API Manual, section 9, and it's about one little struct that gets its whole main-character moment shuttling frames to and from the rings. that's it, that's the vibe. 💅

✨ SYNOPSIS ✨

struct tbstream_frame {
    struct tbstream_dev *sdev;
    struct page *page;
    unsigned int offset;
    bool completed;
    struct ring_frame frame;
 };

like, look at her. five fields. no notes. 🎀

• sdev — Pointer to the stream device. she's literally pointing at the stream device, that's her whole job 🔥
• page — Page holding the packet. the packet lives here, this is its home 🏠
• offset — Offset inside page if partial read is done. iykyk, it's the "we only read part of it" situation 🙈
• completed — true if the RX frame is completed. true!! we love a finished RX frame, no cap ⭐
• frame — Underlying frame structure. the frame under the frame, it's giving layers, it's giving onion 🧅
