I'm not familiar with the madwifi script. What is a VAP? And how comes
that an interface that exists during if-pre-up does not exist during
if-post-down? It seems to me that something has then happened out of
order.

Bug#445356: wireless-tools: post-down script should check if interface still exists

The post-down script should check if the interface still exists. For
example the madwifi script could already have deleted the VAP.
