There should not be any additional allocations, since they are very
slow, that part of mbuf is really horrible for performance - openbsd
hackers removed additional allocation of mbuf tag in PF code during the
last hackathon, which doubled its performance, that is why skb has only
one control structure and data area, which incorporates additional
control information, thus there is no need for multiple destructors.
