These are both identical 10GigE NICs, from dmesg

System: FreeBSD 14.2-RELEASE-p4

When I was chasing that arpresolve warning I saw in the console, I did see some 
discussion like this 
(https://be-virtual.net/pfsense-arpresolve-cant-allocate-llinfo-for-x-x-x-x-on-emx/)
 about funky routers on the other end of the link causing trouble. Since this 
is a newer fiber rollout from my local ISP (Sonic) I wouldn't be surprised if 
there was something funky happening there. Since the LAN-side routing goes 
haywire, I'm thinking that's a red herring.



Cheers
