* Add additional OpenBSD PF graphs Some of these were already present for PFSense (matches, badoffset, fragmented, short, normalized, memdropped) and reuse existing graph types; the others are are added as new types. * collect-snmp-data.php: support IPv6 hosts * Add SNMP data for new OpenBSD OIDs * Stack all OpenBSD PF drops into a single graph/rrdfile * Pull additional drops in to pf_drops The MIB descriptions don't say "drop", but reading the OpenBSD source:c471a73b65/sys/net/pfvar.h (L1196)it's clear that badoff, frag, short, and norm are all drop reasons. Pull them in into the stacked drop graph, too. * ./scripts/save-test-data.php -o openbsd -v pf * Include device_graphs in saved os module test data * Revert "Include device_graphs in saved os module test data" This reverts commita85c902fe9. * Update to use SnmpQuery Co-authored-by: Kevin Wallace <kevinwallace@users.noreply.github.com> Co-authored-by: Tony Murray <murraytony@gmail.com>
