netmap issue with Intel 82574L Network adapter
-
Does anyone know how to get netmap working with Intel 82574L network adapter? I cannot seem to get mine working. It works for a while and then drops the connections. I try to ping google.com and it works for some time, then intermittently it drops the connection.
Doing a ifconfig em0 down; ifconfig em0 up makes it work for a couple of minutes and again it drops.
I am running pfSense-2.3.2
The follow NIC cards are mentioned as not working with netmap in the following post:
https://forum.netgate.com/topic/112300/suricata-netmap-realtekNetmap / FreeBSD has issues with Intel i340, i350/v2, i210, i211, i217 ,i219, PRO/1000, 82575/82576/82579/82580 and Realtek RTL8168B NIC's.
But 82574L is not mentioned, so was inquisitive to know.

Upgrade to 2.4.4. That version is over 2 years old.

Has anyone got this working in 2.4.4...

It's currently running on a hardware which has an Intel I211 network adapter and netmap works smoothly. It's only with Intel 82574L, that netmap stops traffic. However, when I check the netmap(4) and em(4) man pages 82574L seems to be supported.
SUPPORTED DEVICES
netmap natively supports the following devices:
On FreeBSD: em(4), igb(4), ixgbe(4), lem(4), re(4).HARDWARE
The em driver supports Gigabit Ethernet adapters based on the Intel
82540, 82541ER, 82541PI, 82542, 82543, 82544, 82545, 82546, 82546EB,
82546GB, 82547, 82571, 82572, 82573, and 82574 controller chips -

It appears the Intel 82574L driver still has issues with netmap stability.

Thank you, @bmeeks. Let me take this up with FreeBSD then.

Yes.
Could you review /var/log/system.log and /var/log/suricata/suricata_[specific-to-your-interface]/suricata.log for netmap errors and report your findings?
eg cat /var/log/system.log | grep netmap
