Drop CONFIG_IPV6 ?

[Reiner Karlsberg]

Practically always I disable IPv6. First of all, to get rid of stuff, which might be "nice to have", but is not required
"to do the job". The less code I have running, the smaller the probability to run into bugs.
Second, it is a good method to reduce the requirements on flash, when having many non-standard packages installed, i.e. 
squid or PHP.
Third, I often have to connect via wireless WANs, not supporting IPv6 at all.

So, pls do _not_ remove CONFIG_IPV6

Cheers,
