From 10708f37ae729baba9b67bd134c3720709d4ae62 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Thu, 11 Mar 2010 09:57:29 +0000 Subject: net: core: add IFLA_STATS64 support `ip -s link` shows interface counters truncated to 32 bit. This is because interface statistics are transported only in 32-bit quantity to userspace. This commit adds a new IFLA_STATS64 attribute that exports them in full 64 bit.
