IS-IS Error (FRR)

Hi all.

I'm almost there getting IS-IS to work without issue. I'm now faced with
the following error log:

2020/04/17 10:02:01 ISIS: IS-IS bpf: could not transmit packet on em0:
Input/output error
2020/04/17 10:02:01 ISIS: [EC 67108865] ISIS-Snp (1): Send L2 PSNP on
em0 failed

This repeats every second.

Anyone know what this could be?

Systems is FreeBSD-12.1-RELEASE-p3.

Despite the error, IS-IS is running and routing is good, talking to a
Cisco IOS XE implementation on the other side. So the error is throwing
me off.

No feedback from the Slack feed, Google doesn't say much, and waiting to
hear back from the FRR list.
