Any reason why we are with the driver version 3.2.6-k for e1000e, while the latest version available from intel is 3.8.4 ??
Edit :
I just switched my LAN/WAN cables, and this time i set ETH0 as the WAN (the USB3 adapter) and ETH1 as the LAN interface (Intel I217-LM), after several tests i don't have the connexion reset anymore !
But at least one big roller coaster in the curve all the time.
With speedtest.net still no problem, I wonder if there is not a smoothing of the curve that hides the ups and downs :
Back on the Lenovo M920q with the I219-LM this time.
Cables switched :
I219-LM = WAN = eth0
Usb3 adapter = LAN = eth1
The curve is ok, no big roller coaster here. Looks like making the intel NIC the WAN interface is a good workaround, as you don't have to tinker the settings and disable some features. if someone can explain why, it would be interesting...
btw i don't have a RTL8111 usb3 NIC, but a RTL8153, this model

Does anyone know if we can find some oem intel X550-T2 based cards, used and for cheap ?
Maybe HP/DELL/Lenovo...have product codes that I could search for
up to now, all i could find is 210€ for a used card in my country.
Any specific reason for going for the X550 ?
The X540 and X520 are cheaper.
Not sure if any of those are multi gig, but you are probably aware, and don't mind.
I'm using a HPE X540-AT2, and it serves me well, although the kernel I'm
currently on (Fedora 35, 5.15.14), seem to have hw offloading broken, the card
maxes out my 1285Lv4 routing at ~800mbit.
I'm using both ports on the card, one for LAN, the 2nd for WAN.
Broadcom's cheaper here too, look for the 57810S / 57810A, note it exists with dual RJ45s
and SFP+s.
There's also the Supermicro AOC-STG-I2T and HPE 561T.
Because of the multi gigabit 10G/5G/2.5G/1G. My ISP has some offers at 2.5Gbps, and some offers at 8Gbps for which I am not yet eligible in my region, so it may be in 1 or 2 years?
X540 and X520 are 10G/1G
i read somewhere also that the X550 consumme less power, something like 40%. i don't remember where...
here is where i found the info about the power consumption :
One may also notice quickly that the heatsinks on these cards are much smaller than on the X540 generations of cards. The X550 is Intel’s newer generation that is much better on power/ thermals while adding new features. To give some sense, the X540 version of this card is rated at 14.28W with both ports operating at 10Gbase-T speeds. This card is rated at 8.16W. That is around a 43% decrease in power which is a massive generational improvement.
i just received the Pcie Riser and my 4x ports card. i made a mistake and ordered a 4x 1Gbps (Realtek) card instead of the 4x 2.5Gbps one the seller used 1 page to sell 2 different cards with the same 1st picture advertising the 2.5gbps card
i compared with ETHTOOL the settings for both NICs and i found that in the 8111h TSO and some other settings enabled for the intel NIC are actualy disabled in the Realtek NIC
i tried to enable TSO and GSO but it doesn't work ? this tool only works with intel NICs ??
root@OpenWrt:~# ethtool -K eth1 tso on
Could not change any device features
root@OpenWrt:~# ethtool -K eth1 gso on
Could not change any device features
These parameters are not [fixed] so why i can't enable them ??
well finally i could fix this problem with the folowing command :
root@OpenWrt:~# ethtool -K eth1 sg on
Actual changes:
scatter-gather: on
tx-scatter-gather: on
tcp-segmentation-offload: on
tx-tcp-segmentation: on
tx-tcp-mangleid-segmentation: on
tx-tcp6-segmentation: on
generic-segmentation-offload: on

it automagicaly enabled all the settings i wanted, but unfortunately nothing changed during the speedtest...
Just for reference, iperf3 and iperf3 --reverse (that's what I can test easily, as the baytrail-d server only has a single NIC), 'server' running on a j1900 with RTL8168g/8111g, XID 4c0, IRQ 91 client a faster system with RTL8168f/8111f, XID 480, IRQ 27, values consistently between 940 and 944 MBit/s.
Btw., just testing another j1900 with I211 (igb) network cards now, routing is easily possible at ~940 MBit/s (without even breaking ~25-30% load on any core), with sqm the limit seems to be more around 830 MBit/s (one core fully loaded, after tweaking irqbalance and packet steering).
