From eb0cabbd1bebbf41858ded768c9cad8840708447 Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Tue, 23 Apr 2013 06:06:50 +0000 Subject: [PATCH] net/mlx4_en: Support software timestamping Kernel software timestamping requires that the driver calls skb_tx_timestamp just before passing the skb to the HW MAC layer. This patch adds this call. Signed-off-by: Amir Vadai Signed-off-by: David S.
