Intel Ethernet Controller I225-LM Support?

Looks identical to the one shown here: https://forum.netgate.com/post/993924
Check the boot log for errors when the driver tries to attach.Steve

@stephenw10 Found something pretty interesting...
May be a red herring. I do have an onboard intel NIC that was loading fine as em0. I have since disabled it. Error persists whether the onboard nic is enabled or disabled in the bios.
igc0: <Intel(R) PRO/1000 PCI-Express Network Driver> mem 0xe1b00000-0xe1bfffff,0xe1c00000-0xe1c03fff irq 16 at device 0.0 on pci3 igc0: Setup of Shared code failed, error -2 igc0: IFDI_ATTACH_PRE failed 6 device_attach: igc0 attach returned 6 -
@silvercharge There seems to be some type incompatibility between a quad port Broadcom card and the I225-LM installed. When the Broadcom's link state is down, then the igc0 driver can load successfully.
-
Hmm, curious. So it works with the Broadcom NIC still installed but simply not linked?
But, yes, that's some low level failure preventing the driver attaching.

@stephenw10 Agree. Although I have all offloading is disabled in 2.5.2 CEA, a quick search show similar complaints over the years (e.g. intel & broadcom incompatibly).
-
Yeah, no amount of offload disabling is doing to help if the driver doesn't attach.
-
Anyone able to test this in a 2.6 snapshot?
It looks like 2.5.2 missed this fix for UDP checksum offloading.
That is in 2.6.Steve
-
@stephenw10 I'll throw the 2.6 snapshot on a flash drive and test it right now.
Edit: It looks like everything works with the I225-LM NICs on the 2020806 build. Upon fresh installation, DNS and IPv6 were working without making any changes. I navigated to System > Advanced > Networking and verified that the disable hardware checksum offloading option was not checked.
I'm about to head out of town soon so let me know if you want anything specific checked. Otherwise I can dig further early next week.

TSO and LRO should be disabled by default anyway.

So that's all the offloading option at their defaults should work in 2.6.

I was curious of his testing. I ran for years with everything enabled using my 2 port Broadcom LOM on my Dell r220. Never a problem. I understand it's against what is recommended, but the Broadcom drivers for my NICs were mature and handled everything correctly without issue.
-
@slk2k I left everything at the default.
-
Awesome - thanks!!
-
@silvercharge FWIW, in my scenario, I had to ensure that only i225 NICs were installed in a system. If any other NICs, (intel, broadcom, etc.) were installed then the i225 driver would fail to load over 90% of the time. I tested on two distinct systems.

You're gonna need a big CPU!
There is no i225 support in current pfSense. But there will be at some point.
Steve
I JUST now got that, I feel dumb now thanks lolAs for the rest of the post... I'm looking for at least a 2 port 2.5Gb card as internet here is/can/does have that speed for download. The card I originally posted about here just caught my eye. I still have not purchased a 2.5G card as I have seen conflicting information about everyone of them from the traffic graphs not working, cards not supported etc etc...
Are there ANY currently working 2.5Gb cards available that are 100% compatible with pfsense? Preferably one with a built on fan as this is not going into a rack server and case fans do not have enough CFM for the most part for a high bandwidth card. No fan no problem i can add one, it would just make it more plug and pray!

Most of the issues on this thread seem to be from UDP checksum which you can easily disable or run a 2.6 snapshot. We've seen no issues running the i225-V in the 6100.

@stephenw10
on the 6100? sorry confused. -
4 of the i225-V NICs are used in the Netgate 6100. They work fine there.
