Hi,
I'm running -current on Supermicro X9SCL-F with two on-board Gigabit
Intel (82579LM and 82574L)
and one PCI-e 4x Supermicro AOC-SG-I2 [0] (two ports Intel 82575EB).
The question is why 82575EB doesn't support hwfeatures
(CSUM_TCPv4,CSUM_UDPv4 and VLAN_HWTAGGING) as 82579LM and 82574L.
Thanks.

Hi,
Before my previous email I had a strange issue but back then I didn't
know that it
was related to the NIC.
I have a basic ifstated config [1] to monitor my WAN connection (first
port on AOC-SG-I2 was my uplink to my ISP).
At some time ifstated sent me two emails - the link was DOWN and after 9
(nine) seconds was back ON-Line.
I had a few phone calls with my IPS and they checked the switch a few
times.
I started to wonder if the problem was on my side. I plugged the second
port of AOC-SG-I2 to an tp-link wdr4900 which I use
as 5 port gigabit switch for my home LAN and began to observe two ports
with a `while` loop:
[ns]~$ while true; do date; ifconfig emp[1-0] | grep -e "media:" -e
"status:"; sleep 1; done > mon_if_em[1-0]
Both ports had 2-3 seconds disconnects at the same time (two different
switches).
Here's the question - Could this be a hardware related problem or it's a
driver issue?
Is anyone out there also using Intel 82575EB?
That's why I asked for hwfeatures in first email because that's the only
difference I saw.
Now I moved the NIC to another (test) server (dmesg and pcdump at the
end [2]) to test the same way.
em(4) says:
"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."
