Subject: dp83640: use proper function to free transmit time stamping packets
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f5ff7cd1a84caa9545d952a37ac872ccb73825fb;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

dp83640: use proper function to free transmit time stamping packets

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.
