I have a number of discovered Linux devices that are showing their 'Vendor' attribute as "net-snmp - Linux" instead of just "Linux", as expected. An example description from one device (which looks like it was populated by SNMP) says "Linux <SERVERNAME> 4.4.0-171-generic #200-Ubuntu SMP Tue Dec 3 11:04:55 UTC 2019 x86_64". Any idea why this is happening?
