* 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
