Public bug reported:
I've been experiencing an issue with my wireless card and ifup relating
to this script. I have a fix for it and thought the devs here might be
interested.
This is the issue: If a setting fails to be applied, the script brings
the card up and then tries to apply the setting again. This is fine, but
it leaves the card up. Later on in the ifup process other scripts try to
access the card and if the card is up it will respond that it's busy and
ifup fails.
My solution has been to alter the wireless-tools if-pre-up script so
that it ends by running ifconfig down in this case. Here is the patch:
