Subject: [PATCHv2 1/1] ip-link: add switch to show human readable output
Byte and packet count can increase to really big numbers. This adds a
switch to show human readable output.
% ip -s link ls wl
4: wl: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP mode DORMANT group default qlen 1000
link/ether 00:de:ad:be:ee:ef brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
