* Remove `Head` field from `ExtPacket` structure. Although we do not intend to, but if packets get out-of-order in the forwarding path (maybe reading in multiple goroutines or using some worker pool to distribute packets), the `Head` indicator could lead to wrong behaviour. It is possible that at the receiver, the order is - Seq Num N, Head = true - N + 1, Head = true If the forwarding path sees `N + 1` first, the Head flag when it sees `N` packet is incorrect and will lead to incorrect behaviour. The alternative check is very simple. So, remove `Head` flag. * Remove unused field
