From aa7bd467e3db3ddac503d0126a0c021871ca7d88 Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Fri, 4 May 2012 01:55:23 +0000 Subject: [PATCH] ixgbe: support software timestamping Kernel software timestamping requires that the driver calls skb_tx_timestamp just before passing the skb to the MAC, in order to provide the best software timestamps. This patch adds this call for that support.
