Just edit the .config file and use 'oldconfig' instead of
'menuconfig'. I've found that you can also read the .config file and
make a mental note of what options precede or follow the option you
are interested in, then browse the menus to find those options you are
familiar with their location and the option you want will be nearby.
Just because your kernel includes TCP ECN capability doesn't mean you
have to turn it on or use it. If you always want ECN to be off, put
net/ipv4/tcp_ecn = 0
in /etc/sysctl.conf and ECN will be disabled automatically each time
you boot. You can always change it on-the-fly using either 'echo'
(like you did earlier) or 'sysctl'.
