Subject: [250/262] dp83640: use proper function to free transmit time stamping packets

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Richard Cochran <richardcochran@...il.com>

commit f5ff7cd1a84caa9545d952a37ac872ccb73825fb upstream.

The previous commit enforces a new rule for handling the cloned packets
for transmit time stamping. These packets must not be freed using any other
function than skb_complete_tx_timestamp. This commit fixes the one and only
driver using this API.

The driver first appeared in v3.0.
