This patch allows to display the current counter of carrier on<->off
transitions (IFLA_CARRIER_CHANGES, see kernel commit "expose number of
carrier on/off changes"):
ip -s -s link show dev eth0
32: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 ...
link/ether ................. brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast
125552461 258881 0 0 0 10150
RX errors: length crc frame fifo missed
0 0 0 0 0
TX: bytes packets errors dropped carrier collsns
40426119 224444 0 0 0 0
TX errors: aborted fifo window heartbeat transns
0 0 0 0 3
Tested:
- kernel with patch "net-sysfs: expose number of carrier on/off
changes": see "transns" column above
- kernel wthout the patch: "transns" not displayed (as expected)

How to compile this.
--------------------
1. libdbm
arpd needs to have the db4 development libraries. For Debian
users this is the package with a name like libdb4.x-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a Config file which
contains whether or not ATM is available, etc.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
