i40e_unused_pit_index(9)

💖 NAME 💖

okay so bestie, this is the page for i40e_unused_pit_index(9) — its whole thing is finding an unused PIT index for the given list. that's the assignment, and it ate. 💅

✨ SYNOPSIS ✨

u8 i40e_unused_pit_index (struct i40e_pf *pf );

🎀 ARGUMENTS 🎀

• pf — the PF data structure. literally the one argument, and it's giving main character energy. 🫶

🌸 DESCRIPTION 🌸

okay so here's the tea: this function finds the first unused flexible PIT index entry. no cap. ✨

it searches both the L3 and L4 flexible PIT lists so that the returned index is unique and unused by either currently programmed L3 or L4 filters. the way that's lowkey the whole point... iykyk. 🔥

and for storage? it uses a bit field to track which indexes are already used. iconic bookkeeping fr fr. 💖
