Kuniyuki Iwashima cf6c06ac74 net: Introduce net.ipv4.tcp_migrate_req.
[ Upstream commit f9ac779f881c2ec3d1cdcd7fa9d4f9442bf60e80 ]

This commit adds a new sysctl option: net.ipv4.tcp_migrate_req. If this
option is enabled or eBPF program is attached, we will be able to migrate
child sockets from a listener to another in the same reuseport group after
close() or shutdown() syscalls.
