APU3 ethernet can't transmit

[Stefan Bethke]

I have a weird situation with an PCEngines APU3, where I can't seem to be able to transmit packets through either of the igb interfaces. With tcpdump, I can see packets arriving, and the interface flags appear to be just fine:
        options=e527bb<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,TSO4,TSO6,LRO,WOL_MAGIC,VLAN_HWFILTER,VLAN_HWTSO,RXCSUM_IPV6,TXCSUM_IPV6>
        ether 00:0d:b9:58:xx:xx
        inet6 fe80::20d:b9ff:xxxx:xxxx%igb0 prefixlen 64 scopeid 0x1
        inet6 2a02:8108:4840:xxxx:xxxx:xxxx:xxxx:xxxx prefixlen 64 autoconf
        inet 0.0.0.0 netmask 0xff000000 broadcast 255.255.255.255
        media: Ethernet autoselect (1000baseT <full-duplex>)
        status: active
        nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>

dhclient is running on that interfaces, and I got an IPv6 address through RA.

Assigning an address manually doesn't change anything.

igb0 at pci0:1:0:0:        class=0x020000 card=0x00008086 chip=0x157b8086 rev=0x03 hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'I210 Gigabit Network Connection'
    class      = network
    subclass   = ethernet

# freebsd-version
12.2-RELEASE

I installed 12.2-REL a couple of weeks ago, and haven't done anything since.

Tried the three different port with different cables on different switch ports, which are working fine with other machines.

I'm installing updates now via a USB adapter.

Any suggestions?
