void llc_pdu_decode_pf_bit	(	struct sk_buff *	skb,
		u8 *	pf_bit
	)

llc_pdu_decode_pf_bit - extracs poll/final bit from LLC header : input skb that p/f bit must be extracted from it : poll/final bit (0 or 1)

This function extracts poll/final bit from LLC header (based on type of PDU). In I or S pdus, p/f bit is right bit of fourth byte in header. In U pdus p/f bit is fifth bit of third byte.
