Exactly! This is a really really nice card and I don’t get why OpenBSD
doesn’t support the offloading features just as you’ve shown for bge
and re0. Definitely awaiting a response from the devs on this.

Hi,
[...]
ifconfig on my lan port shows:
```

hwfeatures=10<VLAN_MTU> hardmtu 9216

Maybe this is the culprit?
/usr/src/sys/dev/pci/if_em.c:
1893 if (sc->hw.mac_type >= em_82543 && sc->hw.mac_type !=
em_82575 &&
1894 sc->hw.mac_type != em_82580 && sc->hw.mac_type !=
em_i210 &&
1895 sc->hw.mac_type != em_i350)
1896 ifp->if_capabilities |= IFCAP_CSUM_TCPv4 |
IFCAP_CSUM_UDPv4;
It seems as if I350 (among a few other) has an exception for these
features. Maybe it was not tested well enough, or actually it was, and
was failing in this department.
Maybe a developer can add some insight, if this catches their eyes :)
