SO_BINDTODEVICE setsockopt
--------------------------
This is a generic SOL_SOCKET option that can be used to tie AF_XDP
socket to a particular network interface. It is useful when a socket
is created by a privileged process and passed to a non-privileged one.
Once the option is set, kernel will refuse attempts to bind that socket
to a different interface. Updating the value requires CAP_NET_RAW.

network connections you can set this knob to 2 to enable
unconditionally generation of syncookies.
tcp_migrate_req - BOOLEAN
The incoming connection is tied to a specific listening socket when
the initial SYN packet is received during the three-way handshake.
When a listener is closed, in-flight request sockets during the
handshake and established sockets in the accept queue are aborted.
If the listener has SO_REUSEPORT enabled, other listeners on the
same port should have been able to accept such connections. This
option makes it possible to migrate such child sockets to another
listener after close() or shutdown().
The BPF_SK_REUSEPORT_SELECT_OR_MIGRATE type of eBPF program should
usually be used to define the policy to pick an alive listener.
Otherwise, the kernel will randomly pick an alive listener only if
this option is enabled.
Note that migration between listeners with different settings may
crash applications. Let's say migration happens from listener A to
B, and only B has TCP_SAVE_SYN enabled. B cannot read SYN data from
the requests migrated from A. To avoid such a situation, cancel
migration by returning SK_DROP in the type of eBPF program, or
disable this option.
Default: 0
tcp_fastopen - INTEGER
Enable TCP Fast Open (RFC7413) to send and accept data in the opening
SYN packet.
