What is the "Current message level" of an interface that ethtool
provides? E.g.
ethtool eth1
[Other stuff]
Current message level: 0x00000014 (20)
What is the message level? What is message level 20?
This is the level of 'debugging messages/data' from the driver.
It is not quite standardized. Some more documentation is available in Documentation/networking/netif-msg.txt
in your kernel source folder.
You may be able to use ethtool to set the message level
ethtool -s eth1 msglvl [level]
Note that the levels may vary by driver and you should look these up for your specific driver. The mask in a hex (0x... form) or decimal input should be accepted.
ethtool -s eth1 msglvl [level]
