Hash :3064edb0 Message :Reference count the listen inpcb in the TCP SYN cache.
To make progress in unlocking TCP input path, more reference counting
is needed. The SYN cache has a reference to the listen socket in
form of a struct tcpcb. Instead of adding a refcount to tcpcb, it
is easier to use a struct inpcb pointer which already has a refcount.
Acquire and hold the reference while running SYN cache timer.
