t4_rx_hststamp(9)

💖 NAME 💖

okay bestie, say hi to t4_rx_hststamp(9) from the Kernel API Manual. Its official NAME energy is Recv PTP Event Message — that’s the whole lore, and honestly it ate. 💅

✨ SYNOPSIS ✨

Here’s the signature, character-for-character, no edits, no cap:

int t4_rx_hststamp (struct adapter *adapter , const __be64 *rsp , struct
       sge_eth_rxq *rxq , struct sk_buff *skb );

🎀 ARGUMENTS 🎀

the cast, in order:

• adapter — the adapter.
• rsp — the response queue descriptor holding the RX_PKT message.
• rxq — the response queue holding the RX_PKT message.
• skb — the packet.

🦋 DESCRIPTION 🦋

For a PTP enabled and MPS packet, read HW timestamp. That’s the whole description, bestie — short, sweet, and timestamped. 🌸
