First off let me say that I'm not a FreeBSD guru of any type. I'm currently using pfSense 2.4.4 with FreeBSD 11.2-RELEASE-p3. I'm using an Intel E1G44HT I340-T4 4 port PCIe Ethernet Server Adapter that's supposed to have an Intel 82580 controller (from Intel's documentation: https://ark.intel.com/products/49186/Intel-Ethernet-Server-Adapter-I340-T4). The following URL shows that that the igb(4) driver is supposed to be compatible with the ethernet adapter I listed with the 82580 controller: https://www.freebsd.org/cgi/man.cgi?igb(4) . I'm using Suricata with pfSense for an IDPS. I'm receiving netmap_grab_packets messages which I'm told means that FreeBSD is not compatible with my ethernet adapter using Suricata. Would anyone know what may be occurring and how to fix it? Any suggestions would be helpful. Thank you.
