sysctl for TCP windows scaling

[Lloyd Parkes <Lloyd.Parkes%ird.govt.nz@localhost>]

Is it my imagination, or does net.inet.tcp.win_scale completely fail to switch 
TCP window scaling on or off? Maybe this isn't what it's for?

Tcpdump says this "13:35:06.520145 IP 10.40.101.129.65423 > 204.152.190.16.873: 
S 2496279258:2496279258(0) win 32768 <mss 1478,nop,wscale 
3,sackOK,nop,nop,nop,nop,timestamp 1 0>" for the first packet sent, and sysctl 
says this "net.inet.tcp.win_scale = 0".

Cheers
