fc_fill_hdr(9)

✨ NAME ✨

okay so this is fc_fill_hdr(9), straight outta the Kernel API Manual, and it does exactly what it says on the label: it fills in FC header fields based on the request 💅

🎀 SYNOPSIS 🎀

void fc_fill_hdr (struct fc_frame *fp , const struct fc_frame *in_fp ,
       enum fc_rctl r_ctl , u32 f_ctl , u16 seq_cnt , u32 parm_offset );

🦋 ARGUMENTS 🦋

• fp — the reply frame, aka the one holding the header that's getting filled in 🫶
• in_fp — the request frame, aka the one holding the header we're using to fill in the reply ✨
• r_ctl — the R_CTL value for the header 💖
• f_ctl — the F_CTL value for the header, with 0 pad 👑
• seq_cnt — the sequence count for the header; it gets ignored if the frame already has a sequence 🙈
• parm_offset — the parameter / offset value 🎀
