Description of Problem:

neat writes this configuration in ifcfg-eth0 for a DHCP interface:

BOOTPROTO=DHCP

which ifup handles okay, but ifdown bypasses the interface dropping
sequence for DHCP interfaces and ends up leaving dhcpcd running. 
Essentially, the trap looks like this:

if ["$BOOTPROTO" = bootp -o "$BOOTPROTO" = dhcp ]; then
     [ -n "`pidof -x dhcpcd`" ] && {
          dhcpcd -k ${DEVICE}
          retcode=$?
...

you get the idea.  Point is, when neat sets that BOOTPROTO=DHCP, it evades
this trap and the interface is dropped rather messily, leaving dhcpcd still
running.  

There is also one other error associated with this:

Error: an inet prefix is expected rather than "/".

I'm not sure where that is coming from, but it seems related, and it goes
away when you manually fix the ifcfg-eth0 file.


How Reproducible:

Always

Steps to Reproduce:
1. Configure a DHCP interface with neat. 
2. Note the ifcfg-eth0 file has BOOTPROTO=DHCP
3. try to ifdown eth0, and notice the ipcalc errors and that dhcpcd is
still running after the interface is brought down.

Actual Results:

ifdown spews errors and doesn't kill dhcpcd like it should

Expected Results:

clean interface shutdown, with dhcpcd terminated.
