Re: [PATCH] fix tcp_default_win_scale.

[David Ford]

It's been a while since I used a 1460 MTU for PPTP over DSL, but unless 
OSDN got a clue recently, their firewalls drop the ICMP for PMTU 
discovery.  Does anyone have a tool that exercises a bunch of TCP/IP 
options to detect such broken firewalls?
