Subject: net/wireless: ipw2200: Fix panic occurring in
ipw_handle_promiscuous_tx()
From: Stanislav Yakovlev <[email protected]>
commit bf11315eeda510ea4fc1a2bf972d8155d31d89b4 upstream.
The driver does not count space of radiotap fields when allocating skb for
radiotap packet. This leads to kernel panic with the following call trace:
