From mboxrd@z Thu Jan 1 00:00:00 1970 From: Andrew Lunn Subject: [PATCH v2 net-next 1/2] Documentation: sysfs-class-net-statistics: Clarify rx_bytes and tx_bytes Date: Tue, 23 May 2017 23:10:57 +0200 Message-ID: <1495573858-32346-2-git-send-email-andrew@lunn.ch> References: <1495573858-32346-1-git-send-email-andrew@lunn.ch> Cc: Florian Fainelli , hayeswang , netdev , Andrew Lunn To: David Miller Return-path: Received: from vps0.lunn.ch ([178.209.37.122]:42164 "EHLO vps0.lunn.ch" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1162002AbdEWVLi (ORCPT ); Tue, 23 May 2017 17:11:38 -0400 In-Reply-To: <1495573858-32346-1-git-send-email-andrew@lunn.ch> Sender: netdev-owner@vger.kernel.org List-ID: Document what is expected for the rx_bytes and tx_bytes statistics in /sys/class/net//statistics. The FCS should be included in the statistics. However, since this has been unclear until now, it is expected a number of drivers don't. But maybe with time they will.
