Intel I219V Ethernet on ASUS Prime B560-Plus Motherboard

[rrsum]

I have an ASUS Prime B560-Plus motherboard with a 10th generation Intel CPU. The motherboard manual lists the onboard ethernet as an Intel I219V. Version 13.0 (Release) cannot see the onboard ethernet. A search reveiled patch D25035 which is supposed to support that ethernet. I downloaded the patch, applied it to /usr/src/sys/dev/e1000 (and it made the changes), recompiled the em driver (and installed it), and finally rebooted. Still no recognition of the onboard ethernet. Do I need to do something else, or did I do something wrong in the process?

... recompiled the em driver (and installed it) ...

As a module? If so you need to build a new kernel. The em(4) driver is compiled in the kernel:

/usr/src/sys/amd64/conf/GENERIC

device          em                      # Intel PRO/1000 Gigabit Ethernet Family

Yes, I should have done that. However, after recompiling the kernel, I still don't see the onboard ethernet. Here is the result from pciconf -lv:

none4@pci0:0:31:6: class=0x020000 rev=0x11 hdr=0x00 vendor=0x8086 device=0x15fa subvendor=0x1043 subdevice=0x8672
vendor = 'Intel Corporation'
device = 'Ethernet Connection (14) I219-V'
class = network
subclass = ethernet

Also, in order to connect via ethernet, I added an Intel card. Here is it's pciconf report:

em0@pci0:4:0:0: class=0x020000 rev=0x00 hdr=0x00 vendor=0x8086 device=0x10d3 subvendor=0x8086 subdevice=0xa01f
vendor = 'Intel Corporation'
device = '82574L Gigabit Network Connection'
class = network
subclass = ethernet

All this is on 13.0 Release (GENERIC with patch D25035 applied) and the kernel rebuilt with just the same GENERIC conf.

Any suggestions?

The D25035 patch you are referring to is a patch on a driver that's not in 13.0-RELEASE, so it seems you're missing the actual driver. I would suggest giving 13-STABLE a try, support for various Intel 2.5Gbps interfaces have been added to it not too long ago. FreeBSD 13.0-RELEASE doesn't support any 2.5Gbps network cards (it does support various 10Gbps cards).

-STABLE is a supported development version, -CURRENT is an unsupported development version. The -STABLE branches are used to create the next minor releases of a branch. Thus this driver will be included in 13.1-RELEASE, but that's not going to be released any time soon (probably summer next year).

The D25035 patch doesn't include the device ID of your I219V, nor is it listed in releng/13.0, a.k.a 13.0-RELEASE ( sys/dev/e1000/e1000_hw.h). It does in stable/13.

Or run 13.0-STABLE, as SirDice suggested, or If you insist using 13.0-RELEASE, and are using GIT, you can cherrypick from stable/13, or just copy over the e1000 directory, eventually sys/conf/files.

First, thanks for your help on this. Greatly appreciated. Actually, I was trying to cherry pick the driver, hoping the patch would provide the desired result, but not understanding the complexity involved or the additional drivers required. I plan to back off to the release and use a different box to load stable. The working ethernet card will do for now. Again, many thanks.
