From: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Date: Mon, 16 Jul 2012 18:24:41 -0700 > From: Narendra K <narendra_k@dell.com> > > The commit 4197aa7bb81877ebb06e4f2cc1b5fea2da23a7bd implements 64 bit > per ring statistics. But the driver resets the 'total_bytes' and > 'total_packets' from RX and TX rings in the RX and TX interrupt > handlers to zero. This results in statistics being lost and user space > reporting RX and TX statistics as zero. This patch addresses the > issue by preventing the resetting of RX and TX ring statistics to > zero. > > Signed-off-by: Narendra K <narendra_k@dell.com> > Tested-by: Sibai Li <sibai.li@intel.com> > Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Applied, thanks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
