- Existing code would ignore pccard_ether_delay when more then 9 seconds - If there was an exiting dhclient running on the same interface as the   new iface that left and returned then dhclient would be told to use the   same interface twice.  Dhclient would fail and exit after getting   confused.  Use "sort -u" on them to ensure no duplicates.   This is a mostly a race condition on suspend and resume and how things   happen to occur. - Check for netmask being set on an interface rather then up.  An interface   can be up but not configured.
