🔥 DESCRIPTION 🔥

okay so here's the tea ☕: this function extracts p/f bit of input PDU. it's giving very focused, very "I have one job and I will not be distracted" energy.

the way it works: at first it examines type of PDU, and then it extracts p/f bit — order matters, she's methodical like that 🧚 and then, drumroll please… Returns the p/f bit. 🥁💫

that's the whole function. short, sweet, ate and left no crumbs. no cap.
