Done :-) The above mentioned commit has been reverted as i suggested to create a new socket option for *all* sockets. It will show up in 2.6.33 : http://git.kernel.org/?p=linux/kernel/git/davem/net-next-2.6.git;a=commitdiff;h=3b885787ea4112eaa80945999ea0901bf742707f You can get the dropcount control message when enabled by a new socket option. I'll add the support for it in candump to show drops on the console and in log-files, when i'm back in the office ... Have fun with it, Oliver _______________________________________________ Socketcan-users mailing list [email protected] https://lists.berlios.de/mailman/listinfo/socketcan-users
