💖 i40e_write_fd_input_set(9) 💖

okay so this is a page straight out of the Kernel API Manual, and bestie, it's a tiny one but it's lowkey iconic — it's the little helper that shoves a value into the flow director input set register. let's get into it 🫶

✨ NAME ✨

i40e_write_fd_input_set — writes value into flow director input set register 💅

🌸 SYNOPSIS 🌸

void i40e_write_fd_input_set (struct i40e_pf *pf , u16 addr , u64 val );

like that's it. that's the whole signature. no cap. ✨

🎀 ARGUMENTS 🎀

• pf — pointer to the PF struct. yes, the whole PF. she's the main character here 👑
• addr — register addr. this is the address of the register we're about to write to 🎯
• val — value to be written. the actual payload, the moment, the slay 💖

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function writes the specified value to the register specified by addr. simple. elegant. done. 🌈

and which register is it? bestie it's the input set register, and it's chosen based on the flow-type. iykyk 🧚

ngl, it's a one-liner of a description but she ate. no notes. 💅
