====================
net/tcp_fastopen: Fix for various TFO firewall issues
Currently there are still some firewall issues in the middlebox
which make the middlebox drop packets silently for TFO sockets.
This kind of issue is hard to be detected by the end client.
This patch series tries to detect such issues in the kernel and disable
TFO temporarily.
More details about the issues and the fixes are included in the following
patches.
