[Click] wifi problems with click

[Peter De Cleyn]

Hi Povilas,

You probably have a mismatch in the decapsulation of the extended
headers. By default , the new madwifi drivers append Prism2 headers,
so you should use Prism2Decap/Encap instead of ExtraDecap.

I tend to use the atheros descriptors, which you can activate by using:

echo '804' > /proc/sys/net/ath0/dev_type

In order to encapsulate/decapsulate, the AthdescDecap and AthdescEncap
elements can be used. This combination works well for me.

hope this helps,
