From: Alexander Aring Date: Wed, 30 Sep 2015 08:20:11 +0000 (+0200) Subject: ieee802154: 6lowpan: add tx/rx stats X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1c64f147d3cc9bbafe091a7b335ea3ec700186f0;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git 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.
