Never mind. It's freed in the caller. But it does a weird thing:
TODO-list: Clean up p80211_wep->data allocation in p80211knetdev_hard_start_xmit().
It's set to NULL, then memset to zero, then when we call
skb_ether_to_p80211() we again set it to NULL then at the end we check
if it is equal to skb->data (it is not), and we also call kzfree()
instead of kfree(). Load of nonsense.
