When buffer alignmnet is applied, the data pointer of skb taken from cookie will no longer point to the first byte of the actual data. But the skb->data pointer is used in ath6kl_tx_complete() to get the index of the virtual interface which will not give the correct interface index and sometimes may give the following WARN_ON() message. Use packet->buf instead of skb->data to fix this.
