ice_get_first_droptc(9)

💅 ice_get_first_droptc(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for ice_get_first_droptc, and it is a tiny lookup situation with big main character energy. ✨

🌸 NAME 🌸

ice_get_first_droptc — returns number of first droptc

🦋 SYNOPSIS 🦋

u8 ice_get_first_droptc (struct ice_vsi *vsi );

🎀 ARGUMENTS 🎀

• vsi — used to find the first droptc. You hand it the VSI, it goes looking for the first droptc; that's the whole assignment. 🫶

✨ DESCRIPTION ✨

This function returns the value of first_droptc. Periodt. 💅

When DCB is enabled, the first droptc information is derived from enabled_tc and the PFC enabled bits. No cap, that's where it comes from. Otherwise this function returns 0, because there is one TC without DCB (tc0). Literally just tc0 holding it down solo. 😭
