em, I wasn't sure because that variable's a memeber of the sk_buff * passed
into the funtion. That function should be static to the file and is only
called from function rtl8192_hard_start_xmit() but that's a function
pointer which is sort of exported:

        priv->ieee80211->softmac_hard_start_xmit = rtl8192_hard_start_xmit;

Having said that the 'OWN' member is part of the private data:

	struct tx_desc_819x_usb *tx_desc = (struct tx_desc_819x_usb *)skb->data;

Like I say I wasn't sure so played it safe. I guess it's private data so nobody
outside the driver should be messing with that data, and I'm not sure how
public that function is.

I'll read some, ponder a bit and have another go.
