Should we avoid the automatic update of netconsole_target until we can notice all
necessary members of netconsole_target updated automatically?
I had thought about automatic updating of the netconsole_target(i.e. local IP address
and network device).
But I thought that the netconsole(netpoll) can only be related to a network device
because the user of netconsole is free to be able to set local IP address and
MAC address of netconsole and it is difficult to monitor change of local IP address.
So, my patches only updates the network device automatically by using a symbolic link
to the network device in sysfs when the event of NETDEV_CHANGEADDR occurs.
The symbolic link to the network device in sysfs has the same meaning as following change
of MAC address and hardware.
(but I hadn't known the changing ability of MAC address using ip(8) command,
thanks for your info)
Or I propose updating netconsole_taget informations when the network device up/down.
The MAC address and network interface name can be changed when
the network device is disabled.
But, in the case, we must think of the case of changing IP address
because we can change IP address without disabling the network device and
can't hook the event of changing IP address.
How do you think?
Thanks
