Description of problem:
The scripts in the kernel-pcmcia-cs package should kill the DHCP client
("dhclient") when pcmcia/cardbus networking cards are removed.

If not, re-insertion of pcmcia/cardbus network cards will lead to odd results
and intermittent networking failures since, after a few card insert/remove
sequences, multiple dhclient programs will be running and they will conflict
with each other.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. use DHCP for networking
2. insert a pcmcia/cardbus networking card (either wired or wireless) and wait
for it to establish an IP address using DHCP
3. eject the card
4. observe that the dhclient program is *STILL* running despite the network
adapter removal
5. observe that new (competing!) dhclient sessions will be spawned when any
other pcmcia/cardbus network cards are inserted
6. problems with multiple simultaneus dhclient sessions can take hours
(depending on lease times) to conflict with each other but *CONFLICT* they
will--resulting in odd network hangs--very fustrating to debug!!!

Expected Results:  dhclient should be killed when a pcmcia/cardbus network
device is removed
