Tony Murray e8dd72e8db feature: Support fdb table on generic devices (#6902)
* feature: support fdb table on generic devices
refactored code to use snmpwalk_group
refactored ajax table code to use joins and reduce extra queries
add indexes for device_id and port_id, drop primary index
Make all columns sortable
Fix a few other small issues

* Add index for vlan_id since that field can be searched by the user

* fix whitespace

* Rename 197.sql to 198.sql

* set row count for table
