Kernel 5.15.78 TCP syncookie enabled

For a very long time, like forever, the firewall in EasyOS has complained about "TCP syncookie" not supported. I found that it is a missing kernel configuration, so has compiled the 5.15.78 kernel with this enabled:

> Networking support > Networking options 
  │ ┌─────────^(-)───────────────────────────────────────────────────────────────────────────┐ │   
  │ │         [*]     IP: broadcast GRE over IP                                              │ │   
  │ │         [ ]   IP: multicast routing                                                    │ │   
  │ │         [*]   IP: TCP syncookie support      CONFIG_SYN_COOKIES                        │ │   
  │ │         < >   Virtual (secure) IP: tunneling                                           │ │   

The firewall also complained about iptables "state" not supported, or something like that. Fixed, see commit:

...at least, it seems to be fixed.
