ADDITIONAL INFORMATION

There are certain vendors that give different information in CDP and in LLDP, such as Cisco Meraki wireless access Points. These devices properly report their name in LLDP, but not in CDP. Allowing the user to specify the type used for creating ansible_net_neighbors would solve these compatibility issues.
