per-socket keep-alive options for TCP

[Andrew Alcheyev]

Hello everybody.

I have recently examined the keep-alive mechanism in FreeBSD's TCP
stack and found out that it has no tunable variables for keep-alive on
a per-socket basis.

Is anyone interested in a patch like this one?

Alternatively, a patch for FreeBSD may introduce a new kernel option.

I would appreciate any suggestions.
