STRUCT IWL_SAP_CB_DATA(9)

🌸 NAME 🌸

okay so this is struct iwl_sap_cb_data(9), straight out of the Kernel API Manual, and it is literally the header to be added for transmitted packets. that's the vibe. main character struct energy, no cap 💅

✨ SYNOPSIS ✨

struct iwl_sap_cb_data {
    struct iwl_sap_hdr hdr;
    __le32 reserved[7];
    __le32 to_me_filt_status;
    __le32 reserved2;
    __le32 data_len;
    u8 payload[];
};

• hdr — the SAP header. iconic little opener.
• reserved — not used. it's just there looking pretty 🎀
• to_me_filt_status — the filter that matches. Bit CB_TX_DHCP_FILT_IDX should be set for DHCP (the only packet that uses this header). iykyk.
• reserved2 — not used. again, decorative bestie.
• data_len — the length of the payload.
• payload — the payload of the transmitted packet. the actual content, fr fr.
