Description Александр 2016-03-09 13:11:30 UTC
Hi! Rebuild a kernel without 'options INET6'
Nat FreeBSD 10.2-RELEASE-p12 admin@nat:/usr/obj/usr/src/sys/GENERIC amd64

Have downloaded and installed the latest driver ix-3.1.14 for X520-DA2

In loader.conf added:

After loading OS in /log/messages:
Mar 4 14:07:37 nat kernel: link_elf_obj: symbol undefined in6_cksum_pseudo
Mar 4 14:07:37 nat kernel: KLD file if_ix.ko - could not finalize loading

And accordingly, loaded the old driver.
In /log/messages:
Mar 4 14:07:37 nat kernel: ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.8.3>

If the kernel is compiled with 'options INET6' what I need, no problem.

It looks like the module wasn't rebuilt with the new kernel configuration.

Can you post your kernel configuration here just to make sure things are being rebuilt?
Comment 2 Александр 2016-04-06 18:14:49 UTC
(In reply to Sean Bruno from comment #1)
Because the kernel configuration removed only 'options INET6'
Comment 3 Jeff Pieper 2016-04-07 15:40:43 UTC
Thanks for the report. Without options INET6 defined in the kernel, removing the -DINET6 flag from the Makefile should allow the driver to load, but it doesn't compile:

We will investigate.
Comment 4 Bjoern A. Zeeb freebsd_committer 2019-05-21 19:00:38 UTC
Just to clarify, this was trying to compile an out-of-tree driver?
Comment 5 Piotr Pietruszewski 2019-05-22 14:23:15 UTC
This is probably bug for out-of-tree driver since in-kernel driver never had 3.1.14 version (after 3.1.13-k version there was 3.2.12-k version).

This problem was resolved in 3.2.0 out-of-tree driver.

I was just trying to get confirmation before closing it.

So thanks for the update.  I didn't expect you even solved that :)
