MIBS were downloaded from Watchguard website:
Icon already exists.
Tested and confirmed in #803
Initial start on better watchguard support
Added hardware into os for fireware
Merge branch 'master' of github.com:laf/librenms into issue-803
Updated this to use just sysDescr
Shouldn't includes/discovery/os/watchguard.inc.php say fireware instead of firebox?
Watchguard support was already in place. Left as is to maintain any backwards compatibility and created the new os definition to match the actual os name the devices used.
