Yes, I'm running opnsense in Hyper-V, the LAN NIC is 2 GBs aggregated in windows server
I'm using two dlink DUB-1312 aggregated. in Untangle was working fine for the last 4 years it was showing 2 GBs NIC but in opnesne the lan and wan showing 10 GBs, I'm not sure if this is a driver related issue? or it is not designed to recognize 802.3ad protocol?

Hmm that possibly gets into what FreeBSD supports on a particular NIC, would have to research that

I've no OPNsense in a vm. We have Deciso full hardware and we had the same problem.
I've juste add the WAN interface in the Intrusion Detection settings and now the log went silent about this problem.

I hope it'll help

I've started another thread about that because I had a combination of problem after the upgrade:

yes it says  under that box to make sure the virtual driver supports this feature
If you are not on a vm, is your date and clock working correctly, check dashboard
That will stop it, just some easy checks
