STRUCT QLINK_CMD_CHAN_SWITCH(9)

🦋 NAME 🦋

okay so bestie, welcome to the Kernel API Manual page for struct qlink_cmd_chan_switch(9) — literally just the data payload for the QLINK_CMD_CHAN_SWITCH command. that's the whole thing. that's the assignment. 💅✨

🎀 SYNOPSIS 🎀

struct qlink_cmd_chan_switch {
    struct qlink_cmd chdr;
    struct qlink_chandef channel;
    __le64 flags;
    __le32 n_counter_offsets_beacon;
    __le32 n_counter_offsets_presp;
    u8 beacon_count;
    u8 rsvd[3];
};

like… look at her. iconic layout. no cap. 👑

so the page only spells out three of these for us, and we do not make stuff up around here, so:

• channel — the channel to switch to. that's the destination, the main character, the whole reason we're here. 🌸
• flags — flags to control the channel switch, as a bitmap of enum qlink_chan_sw_flags. bit math girlies rise. 🔥
• beacon_count — the number of beacons until the switch. it's giving countdown. it's giving anticipation. ⏳

ngl the struct also has chdr, n_counter_offsets_beacon, n_counter_offsets_presp and rsvd[3] sitting in there, but this page does not document them, so we are not gonna invent lore about them. go read ./drivers/net/wireless/quantenna/qtnfmac/qlink.h if you're nosy (affectionate). 🧚

first of all, go touch grass in the kernel file itself: ./drivers/net/wireless/quantenna/qtnfmac/qlink.h — and then get comfy, because this is the entire qlink extended universe, in order, no skips, no shuffle:

like… that's a lot of friends. anyway. 🫶

that's the page, bestie!! it lives out of ./drivers/net/wireless/quantenna/qtnfmac/qlink.h, it's stamped October 2026, and it will be answering to struct qlink_cmd_chan_switch(9) forever. go switch some channels responsibly. mwah. 💖🎀🦋
