NBASE-T Support for Intel X550

I agree, let me see what I can do here....

@stephenw10 I can confirm that setting

sysctl dev.ix.X.advertise_speed=N

Where X is the interface number (e.g. for ix0, X=0 in the command above) and N is the sum of the advertised speeds, works.

In hex and decimal:

Control advertised link speed using these flags:
    0x1 - 1 - advertise 100M
    0x2 - 2 - advertise 1G
    0x4 - 4 - advertise 10G
    0x8 - 8 - advertise 10M

    0x10 - 16 - advertise 2.5G
    0x20 - 32 - advertise 5G

    100M and 10M are only supported on certain adapters.

My default value was 7, (in decimal, so it was 1+2+4, 100M/1G/10G) so to add advertisement of 2.5G and 5G on ix0, I ran:

sysctl dev.ix.0.advertise_speed=55

Since 7 + 16 + 32 = 55.

Now I see:

I also had to add dev.ix.0.advertise_speed as a system tunable, with value 55, to make it persist between reboots

@indigo88
Thank you.

I can confirm that setting 55 works fine on my cards also. Actually it's 1+2+4+16+32
8 (10M) not supported AFAIK on those cards.

indigo88

@w0w Right, the default of 7 is the result of 1 + 2 + 4 (100M/1G/10G)

It’s nice that we have the option, even if it’s a bit esoteric. Also nice that the GUI displays the link speed properly once it’s enabled

I just slotted an X550-T2 into my pfSense box on 2.7.0 and just wanted to chime in that it appears to be advertising NBASE-T speeds despite me not having added the system tunable. When I go to Interfaces > LAN, in the dropdown box for Speed and Duplex, along with autoselect, I have 10G, 5000, 2500, 1000BASE-T and 100BASE-TX all available for selection as media supported by this interface. I have yet to verify that it will link at anything above 1G, but will do so once I have something to try.

For what it's worth, it's a relatively new (2022 date of MFG) card and dmesg states:
ix0: Option ROM V1-b1313-p0 eTrack 0x80000760 PHY FW V523

I'm not sure what that corresponds to firmware-wise, but maybe it can be used for comparison. If there's anything you can think of that I can run from the shell for more detail, feel free to let me know.

@DeviceMangler
The current actual issue and mentioned system tunable is not related to what you see in the speed and duplex dropdown list. Issue is related to autonegotiation, all three X550-T2 I have, shows those NBASE-T speeds in drop-down list as well. The problem is that it does not negotiate on the correct speed, when using NBASE-T switch, and you should select it manually. When system tunable is added, the card automagically connects on the maximum NBASE-T speed. There is no new revisions of X550-T2 and never to be released AFAIK.

DeviceMangler

@w0w
Ah, all right. I assumed that the dropdown box wouldn't have the entries for the other speeds without the system tunable. Thought it may be firmware-related.

Guess I'll go ahead and add the tunable, then.

Thanks!

I am new to pfsense and plan build a router and install pfsense in the next few months. Hardware is atom c3758 with the dual 10gb ports. The c3000 soc has the intel x553 lan controller. Does anyone know if the modifications described here will allow for nbase-t on those ports like on the x550 cards?

stephenw10

AFAIK this works only on the x550 NIC. I do not expect it to work on the x553 NICs that are part of the C3K SoC. It does not work on the 7100 for example.

JBD

Ok and Thank you. Well it works on the x550 which can be had and I may have an opportunity to use an X710-t2l. It is 8 lane (I assume intel wanted to use the same board for the 2 port and 4 port which needs 8 lanes to save on costs), but pcie 3.0 with 4 lanes is all that is needed for a 2 port card and I have understand that it will work in a 4 lane slot at full speed. If it did not, there is always the intel i226.

It's a bit of a bummer that the Intel X550-T2 is not a drop in part for latest version of pfsense without going through some hacks and tweaks. So makes me wonder are we better off going with a different card that has better support in FreeBSD? My concern is since you guys had to go through all of that just how safe is it going to be in future FreeBSD updates? I.e. removal of unsupported drivers.

I recently purchased a couple of I350-T4V2 DELL/INTEL cards off of e-bay and about to replace my older quad NIC in my pfsense whitebox firewall when I realize because I have a paid support for pfsense plus Netgate will only transfer the TAC lite over to the new Netgate Hardware ID as one time courtesy. Lesson learned for me is to only buy one year of TAC Lite instead of two since I like to tinker hardware often.

I'll search another thread for recommendation of a different card that will support 1,2.5,5 and 10 gig copper. Really wish consumer cable modems would have SFP+ ports which would make things alot easier. Ah well.

stephenw10

As far as I know the X550-T is the only card that supports N-Base-T and works in pfSense.

If you know you're going to have to change your NDI you should email support in advance to check. There is some flexibility there.

Darkk

@stephenw10 Yep. I've opened a support ticket with Netgate and they told me will transfer the TAC Lite to a new hardware ID.

Also looks like Intel-X710-T2L is also supported without the hacks.

Interesting, I wonder who you got in support. I didn't expect a response today, however I did get a response and..

I was told this morning (after a hardware change) that Netgate would not transfer to the new NDI.

I opened a ticket with Netgate support several days ago and they said they will do it as a one time courtesy.
