So I upgraded to RC1 this morning. Suricata stops after starting with the error

Sensei starts and runs but shows no interfaces selected. I use igb0 on Suricata for my wan and igb1 on Sensei for my lan.
Forgot to add this was all working on 19.1 before the upgrade. I have 16gb of ram and i5-7600k, 6 ports of intel i211.

Found the below in the general logs. I do have tunables set for the nic that were working fine in 19.1
hw.igb.rxd 4096
hw.igb.txd 4096
net.link.ifqmaxlen 8192
hw.igb.max_interrupt_rate 64000
I'll try removing those when I get a chance but not sure if they are the culprit.

Nice catch, ring size is still too small on stock FreeBSD.
We have the patch on versions up to 19.1, but had to revert for merging newer netmap code in 19.7 and it wasn't applied on top again.

Will be fixed in 19.7 release. Thanks!
Cheers,

Thanks I got it going for now by just dropping my tuneables a bit
Set them to below
hw.igb.rxd 1024
hw.igb.txd 1024
net.link.ifqmaxlen 2048
Both services are working. I'll change them back once 19.7 releases.

Upgrading to 19.7 production this morning (thanks for the great work btw!) I'm having similar issues with netmap (suricata) as @donatom3 above. There is a quadport Intel 82571EB network card (working with the em driver) in my box netmap has problems with:
Jul 18 15:14:40 suricata[51428]: [100151] <Error> -- [ERRCODE: SC_ERR_INITIALIZATION(45)] - Engine initialization failed, aborting...

hw.em.rxd is 1024 (default value)
hw.em.txd is 1024 (default value)
net.link.ifqmaxlen is 2048 (was 50 by default)
Could you guys give any advice on how to remedy this or what could be the problem?
Thanks!
[edit]
Jumbo frames seem to be the issue:
786.356550 [2157] netmap_buf_size_validate error: large MTU (9000) needed but em0 does not support NS_MOREFRAG
786.371958 [2157] netmap_buf_size_validate error: large MTU (9000) needed but em1 does not support NS_MOREFRAG
Strange thing is that this was working before like this. Does anybody know if the updated netmap can work with jumbo frames if the card/driver does not support NS_MOREFRAG?
