Subject: xio: avoid trying bind to port we know will fail
X-Git-Tag: v10.1.0~370^2

xio: avoid trying bind to port we know will fail

When going over range from port_min to port_max to find open
port to bind we can increase port_min after successful bind so the
next portal will start looking from the next port.
