Hi Dave and other maintainers,

can you take a look at and potentially merge patches 1-30 while we
discuss the sctp refactoring?  It would get a nice headstart by removing
kernel_getsockopt and most kernel_setsockopt users, and for the next
follow on I wouldn't need to spam lots of lists with 30+ patches again.
