Much like all other listening socket options, "reuseport" have to
be specified only once, usually in a default server for a listen
socket in question. That is, if you have many servers listening
on port 80, you should write something like:
listen 80 reuseport;
listen 80; # no options here
To check if reuseport actually works just check how many listening
sockets were created - normally there will be just one,
but with reuseport you'll see multiple listening sockets, one for
each of nginx worker processes. Something like "ss -nlt" should
show listening sockets on Linux.
