Hi,
I am running OpenBSD 6.3 with a PCI-Express Intel i350T4 Network card.
The card is detected with the em(4) driver but upon looking at the
hwfeatures with ifconfig I notice that none of the offloading features
the card supports are enabled. Looking at the documentation for the
em(4) driver it states that it supports most of the offloading features:
```
“The em driver supports IPv4 receive IP/TCP/UDP checksum offload and
transmit TCP/UDP checksum offload on all but
82542-based adapters, VLAN tag insertion and stripping, and jumbo frames
on all but 82562V, 82566DC/82566DM
and 82573E/82573L/82573V-based adapters. The 82562V Ethernet controller
chip only supports 10/100 media types.”
```
Yet none are enabled. Any ideas how to get them enabled on OpenBSD?
My pertinent dmesg(8) output related to the i350:
```
em1 at pci19 dev 0 function 0 "Intel I350" rev 0x01: apic 2 int 16,

```
ifconfig on my lan port shows:
