Sysctl.conf parameters "net.inet.tcp.inflight.enable: 3"

[ajg]

the sysctl.conf of  pfsense 1.2 
has the parameter
net.inet.tcp.inflight.enable: 3

should this be 1 ?

I have not come across the value 3 in tuning. It it a modified value?

thanks

That was something one of the developers was messing with at one point, 3 does the same thing as 1, it should be set to 1 though to make sure it continues to function as desired in future releases. I just changed it.
