Hi guys,

I just upgraded a FreeBSD 9.1 box to 10.0 and i found something rather 
odd, the kern.ipc.somaxconn option is missing. Was there anything 
changed or am i missing something, as i wasn't able to find anything on 
google regarding this one.

I rebuilt the kernel with ipfw support but that's pretty much it. I saw 
somaxconn missing from the generic kernel as well.
