* 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 commit a85c902fe9.
* Update to use SnmpQuery
