Recently updated to 21.7.6 from 21.7.5 and after doing so I am running into errors.  Initially my LAN would stop routing traffic and I started noticing errors in dmesg and on screen.  I also noticed the same errors when modifying IDS/IPS.  Which made me think it might be the new IDS/Suricata update causing the issue.

I am running:
OPNsense 21.7.6-amd64
FreeBSD 12.1-RELEASE-p21-HBSD
LibreSSL 3.3.5
CPU: AMD Ryzen 5 2400G
NICs: Intel I350-T4
RAM: 16GB

I noticed in dmesg the following:

generic_netmap_dtor        Emulated netmap adapter for igb0_vlan40 destroyed
generic_netmap_attach     Emulated adapter for igb0_vlan40 created (prev was NULL)
generic_netmap_register   Emulated adapter for igb0_vlan40 activated
iflib_netmap_config             txr 4 rxr 4 txd 1024 rxd 1024 rbufsz 2048

After doing some research I have tried a few things.

1. Revert back to 21.7.5 (issue still persisted)
2. Revert suricata (issue still persisted)
3. Revert os-etpro-telemetry (issue still persisted)
4. Reinstalled back to 21.7.6 and all updates.
4. Reinstalled Kernel (issue still persisted)
5. Tuned I350 Gigabit Nic with  (issue still persisted, removed settings):
     dev.igb.0.iflib.override_ntxds="4096"
     dev.igb.1.iflib.override_ntxds="4096"
     dev.igb.0.iflib.override_nrxds="4096"
     dev.igb.1.iflib.override_nrxds="4096"
6. Tried to ensure that intel drivers were loaded during boot with adding if_igb_load="YES" to /boot/loader.conf  (issue still persisted, kept setting)

After all that, the issue still persists, not sure what else to do at this point. Not much information on iflib_netmap_config....  Any suggestions?
