From 8bcdeaff5ed544704a9a691d4aef0adb3f9c5b8f Mon Sep 17 00:00:00 2001 From: Willem de Bruijn Date: Mon, 19 Aug 2013 16:40:22 -0400 Subject: [PATCH] packet: restore packet statistics tp_packets to include drops getsockopt PACKET_STATISTICS returns tp_packets + tp_drops. Commit ee80fbf301 ("packet: account statistics only in tpacket_stats_u") cleaned up the getsockopt PACKET_STATISTICS code. This also changed semantics. Historically, tp_packets included tp_drops on return. The commit removed the line that adds tp_drops into tp_packets. This patch reinstates the old semantics.
