fc_fcp_send_data(9)

💅 fc_fcp_send_data(9) — Kernel API Manual 💅

🌸 NAME 🌸

fc_fcp_send_data — send SCSI data to a target 💖

✨ SYNOPSIS ✨

int fc_fcp_send_data (struct fc_fcp_pkt *fsp , struct fc_seq *seq ,
       size_t offset , size_t seq_blen );

🎯 ARGUMENTS 🎯

• fsp — the FCP packet that this data is on, bestie.
• seq — the sequence this data is getting sent on.
• offset — the starting offset for this data request.
• seq_blen — the burst length for this data request.

🦋 DESCRIPTION 🦋

okay so the vibe is: this gets called after a Transfer Ready data descriptor has been received. If the LLD is capable of sequence offload, then send down the seq_blen amount of data in a single frame. If it isn’t, then send multiple frames of the maximum frame payload supported by the target port. periodt ✨
