I took a first pass over this and it looks very good.

For the package name then sun.net.extnet repeats "net" and maybe 
sun.net.ext would be better.

For the BaseExtendedSocketOptions then I think the FileDescriptor 
parameter should be the first parameter as that is the file descriptor 
to the socket that the methods operate on.

In ExtendedSocketOptions then I assume the toString is not needed in 
checkValueType.

There are "TODOs" in the tests and I assume it would be better to drop 
those and instead create an issue in JIRA to be addressed once jtreg is 
promoted with support for -limitmods.

There is also a TODO in Sockets.java "check this is working ok" that I 
assume needs attention before this is pushed.
