qbman_pull_desc_set_channel(9)

okay so bestie, gather round the group chat: this is qbman_pull_desc_set_channel from the Kernel API Manual, and it’s lowkey the little function that tells a pull dequeue descriptor which channelid the dequeue command should dequeue from. no cap, it’s giving “one job, done slay” 💅✨

✨ NAME ✨

qbman_pull_desc_set_channel — sets the channelid from which the dequeue command dequeues. that’s the whole vibe: the descriptor gets its channel id set, and the dequeue command knows what channel it’s dequeuing from. iconique 🎀

🦋 SYNOPSIS 🦋

here’s the signature, bestie — do not retype it wrong, this is kernel API and we respect the punctuation:

void qbman_pull_desc_set_channel (struct qbman_pull_desc *d , u32 chid ,
       enum qbman_pull_type_e dct );

💖 ARGUMENTS 💖

okay so there are three arguments, one for each little piece of this operation, and yes every single one matters:

• d — the pull dequeue descriptor to be set. this is the struct catching the update, your main character descriptor 💅
• chid — the channel id to be dequeued. literally the channel id that is to be dequeued, periodt 🌀
• dct — the dequeue command type. like, which type of dequeue command this is, okay? keep it exactly as the API says 🫶
