Description Vic 2007-03-23 10:53:03 UTC 
Description of problem:

Removing a PCMCIA network card (specifically, a WiFi card) doesn't call ifdown
on the interface. This leaves things running (like dhclient), and the card
doesn't then start up properly on re-insertion.

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

Checked on hotplug-2004_04_01-7.7, but this is probably common to many releases.

How reproducible:

Every time

Steps to Reproduce:
1. Insert card & get network running on it
2. Remove card
3. Re-insert card
  
Actual results:

Network doesn't run on that card

Expected results:

Network should run on that card

Additional info:

I patched /etc/hotplug/net.agent - attached.
