Minion not working anymore after update to 12.2

[Andrea Venturoli]

Hello.

A minion of mine stopped connecting to the master after I upgraded it to 
12.2.

Error follows:

I tracked it down to interface em1 being without an IP address (since it 
has vlan childs).
This was not a problem on 12.1. I have other hosts with a similar setup 
that I have yet to upgrade: when I'll be able, I'll see if they all show 
the problem or not.

I have INET6 commented in the kernel config.

Meanwhile, is this something I should report as a FreeBSD bug or upstream?
Any workaround?

  bye & Thanks
