From 1c64f147d3cc9bbafe091a7b335ea3ec700186f0 Mon Sep 17 00:00:00 2001 From: Alexander Aring Date: Wed, 30 Sep 2015 10:20:11 +0200 Subject: [PATCH] ieee802154: 6lowpan: add tx/rx stats This patch adds support for increment transmit and receive stats. The meaning of these stats are IPv6 based, which shows the stats after running the 6lowpan adaptation layer (uncompression/compression, fragmentation handling) on receive and before the adaptation layer when transmit.
