RT_PRIV_IOCTL interface is down Kern.err

The kernel log for my GL-MT3000 router is filling with the following messages. The router seems to be working normally. What does this mean and how do I stop message filling logs?

The problem is related to the iwinfo command. Every time this command is run the kernel throws the “RT_PRIV_IOCTL interface is down” error
