From: Keiichi KII <[EMAIL PROTECTED]> This patch contains the following changes.
To add port dynamically, create "add" element in /sys/class/misc/netconsole. ex) 1. echo "eth0" > /sys/clas/misc/netconsole/add then the port is added with the default settings. 2. echo "@/eth0,@192.168.0.1/" > /sys/class/misc/netconsole/add then the port is added with the settings sending kernel messages to 192.168.0.1 using eth0 device. -+- /sys/class/misc/ |-+- netconsole/ |--- add [-w-------] If you write parameter(network interface name | or one config parameter of netconsole), The | port related its config is added |--- port1/ |--- port2/ ...
