idpf_rx_hwtstamp(9)

🌸 NAME 🌸

okay so bestie, this is idpf_rx_hwtstamp(9) from the Kernel API Manual — and the function is literally idpf_rx_hwtstamp - check for an RX timestamp and pass up the stack. no cap, that's the whole vibe. ✨

✨ SYNOPSIS ✨

here's the signature, copied exactly because we do not play with types, periodt:

void idpf_rx_hwtstamp (const struct idpf_rx_queue *rxq , const struct
       virtchnl2_rx_flex_desc_adv_nic_3 *rx_desc , struct sk_buff *skb );

it returns void, so there's no return-value drama to obsess over, bestie 💅

🫶 ARGUMENTS 🫶

okay the cast of characters is literally right here:

• rxq — pointer to the rx queue that receives the timestamp. she's the queue carrying the timestamp vibe 🎀
• rx_desc — pointer to rx descriptor containing timestamp. the descriptor with the timestamp inside, iykyk
• skb — skb to put timestamp in. this is the skb getting the timestamp dropped into it 🦋
