From d7be81a5916bdb1d904803958e5991a16f7ae4b2 Mon Sep 17 00:00:00 2001 From: Lino Sanfilippo Date: Sun, 27 Mar 2016 12:22:02 +0200 Subject: [PATCH] ravb: fix software timestamping In ravb_start_xmit dont call skb_tx_timestamp only when hardware timestamping is requested: in the latter case software timestamps are suppressed and thus the call of skb_tx_timestamp does not have any effect. Instead call skb_tx_timestamp unconditionally in ravb_start_xmit, since the function checks itself if software timestamping is required or should be skipped due to hardware timestamping.
