Will do.

That and  sysctl_tcp_mtu_probing are on my todo list, assuming the 
general direction is accepted, of course.

Specifically, I couldn't understand why sysctl_tcp_ecn is documented to 
be a boolean value, but is initialized to 2 and queried with if 
(sysctl_tcp_ecn == 1) so I decided to let it be until I figure it out...

Will do. Note that the patch I have still has an ugly bit that needs 
addressing - it sets the features by name, but right now only displays 
numeric values to the, for "show". This of course will be fixed, but it 
does work for testing.

Thanks,
Gilad
