It's a "feature" of apmd. In particular, look at
/etc/sysconfig/apmd
and modify the line labeled: NET_RESTART
In short, when your machine goes into suspend mode, the machine
(when NET_RESTART=yes, the default), will shutdown network interfaces, and
then presumably restart them when the machine "wakes up". I've had
nothing but troubles with it personally, so I always set NET_RESTART=no
