Date: Tue, 21 Jan 2014 13:48:50 +0200 From: Sergey Popovich <popovich_sergei@...l.ru> To: netdev@...r.kernel.org Subject: [PATCH 3/4] ipv4: use SNMP macro assuming softirq context in ip_forward(). ip_forward() runs entirely in softirq context, we could use version of SNMP macro which updates stats counters assuming that.
