My output of dmesg is in http://www.informatik.tu-muenchen.de/~haering/rl_patch.tar.gz >Fix: apply the patch from http://www.informatik.tu-muenchen.de/~haering/rl_patch.tar.gz which checks the return value of rl_encap() instead of cheerfully ignoring the error ;-) This was a quick hack last night, and *not* a patch to really get rid of the bug(s) in the driver. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
