There are a couple of open bugs found by syzkaller (complete with
reproducers) that appeared when I enabled the alternate TCP stacks:

https://syzkaller.appspot.com/bug?id=986b4cecd84439df9794bda1a45d9cf0f50356fe
https://syzkaller.appspot.com/bug?id=048f650e99696f881872a285cef0e3b9bd4f4e25

I'd expect these to be fixed before providing the alternate stacks in
GENERIC.
