This patch uses the new features of the kernel's netlink CAN interface
making the bus-error reporting configurable and allowing to retrieve
the CAN TX and RX bus error counters via netlink interface. Here is the
output of my test session showing how to use them:
# ip link set can0 up type can bitrate 500000 berr-reporting on
# ip -d -s link show can0
2: can0: <NOARP,UP,LOWER_UP,ECHO> mtu 16 qdisc pfifo_fast state UNKNOWN qlen 10
link/can
can <BERR-REPORTING> state ERROR-PASSIVE (berr-counter tx 128 rx 0) restart-ms 0

Furthermore, the missing support for one-shot mode has been added.

Primary site is: http://developer.osdl.org/dev/iproute2 Original FTP site is: ftp://ftp.inr.ac.ru/ip-routing/ How to compile this. -------------------- 1. Look at start of Makefile and set correct values for: KERNEL_INCLUDE should point to correct linux kernel include directory. Default (/usr/src/linux/include) is right as rule. 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 Berkely database routines. Often this is in the db-devel package. 2. make The makefile will automatically build a file Config 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. Stephen Hemminger shemminger@osdl.org Alexey Kuznetsov kuznet@ms2.inr.ac.ru
