be a callable returning a protocol instance.

socket family AF_INET, socket.AF_INET6 or socket.AF_UNIX depending on
host (or family if specified), socket type SOCK_DGRAM.

reuse_address tells the kernel to reuse a local socket in
TIME_WAIT state, without waiting for its natural timeout to
expire. If not specified it will automatically be set to True on
UNIX.

reuse_port tells the kernel to allow this endpoint to be bound to
the same port as other existing endpoints are bound to, so long as
they all set this flag when being created. This option is not
supported on Windows and some UNIX's. If the
:py:data:`~socket.SO_REUSEPORT` constant is not defined then this
capability is unsupported.

allow_broadcast tells the kernel to allow this endpoint to send
messages to the broadcast address.

sock can optionally be specified in order to use a preexisting
socket object.
