sfp_upstream..._signal_rate(9)

okay bestie, welcome to the sfp_upstream..._signal_rate(9) page from the Kernel API Manual ✨ no cap, this one is short and sweet.

🌸 NAME 🌸

sfp_upstream_set_signal_rate — set data signalling rate. 💅

✨ SYNOPSIS ✨

void sfp_upstream_set_signal_rate (struct sfp_bus *bus , unsigned int
rate_kbd );

🎀 ARGUMENTS 🎀

• bus — a pointer to the struct sfp_bus structure for the sfp module. 🫶
• rate_kbd — signalling rate in units of 1000 baud. ⭐

💅 DESCRIPTION 💅

This function configures the rate select settings on the SFP module for the signalling rate (not the same as the data rate). 🚨 Like, please don't confuse signalling rate with data rate, bestie — the page literally says they're not the same. 😭
