This actually addresses a situation of memory corruption
and illegal reference panics, correct?
It prevents TCP input from "reading" bogus memory when comparing
time_wait buckets to the saddr/sport/daddr/dport of an incoming
packet.
By bogus memory I mean it's some large offset from the base of the
struct tcp_tw_bucket structure, past it's end.
