Fix ip_monitor example #290

Closed WGH- closed 1 year ago

WGH- commented 1 year ago

List of groups that's specified in nlgroup field of the address is actually a bitfield, whereas `RTNLGRP*` constants are 1, 2, 3, etc, so they must be shifted before using them in nl_group.

See iproute2 source for example[1][2].
