I'm having trouble using the second NIC interface in a bridge to provide
network connectivity to bhyve VMs and need some help figuring out what is
wrong.

The system is an AMD Ryzen mini-pc (UM250) with two RealTek gigabit NICs
(8168/8111). The second NIC (re1) is a member of a bridge. A configuration
similar to this works on a different system with Intel NICs, but on this
system, the VMs aren't able to connect to the network. I've done the easy
things and verified, for example, the interface can pass traffic (i.e.
hardware, cable, switch are fine). There are some additional "odd" things.
For example, ifconfig doesn't configure an address or even enable the
interface. E.g.,

# ifconfig re1 10.0.0.10/24 up
# ifconfig re1
re1: flags=8902<BROADCAST,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500

options=82099<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>
        ether 1c:83:41:28:c9:e4
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

The command does appear to enable/disable the port:
# tail -f /var/log/messages
Nov 22 08:31:03 stargate kernel: re1: link state changed to DOWN
Nov 22 08:31:11 stargate kernel: re1: link state changed to UP

Note that setting the interface's address from rc.conf works, but after the
system boots, setting the address from the command line doesn't. What else
should I check?

# ifconfig -a -G lo
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
