Date: Thu, 06 Dec 2012 05:25:05 -0000 From: Paul Chavent X-Patchwork-Id: 204282 Message-Id: <1354807505-21222-1-git-send-email-paul.chavent@onera.fr> To: jdike@addtoit.com, richard@nod.at, user-mode-linux-devel@lists.sourceforge.net, netdev@vger.kernel.org, richardcochran@gmail.com Cc: Paul Chavent This new version moves the skb_tx_timestamp in the main uml driver. This should avoid the need to call this function in each transport (vde, slirp, tuntap, ...). It also add support for ethtool get_ts_info.
