I am trying to build the network driver for Intel X710-da2, which can be downloaded here on FreeBSD 9.3.

I followed the Intel README but nevertheless I retrieve the following compile error after running the make command:

Warning: Object directory not changed from original /usr/home/miadmin/ix-2.8.2/src

if_ix.c:2600: error: (Each undeclared identifier is reported only once
if_ix.c:2600: error: for each function it appears in.)
*** [if_ix.o] Error code 1

What might be the problem for these errors?

My final goal is it to compile the driver in order to integrate it (later on, as described here) in my FreeNAS 9.3 environment since the integrated driver has issues (Bug #9117) with the X710-da2 network card.

Thank in advance for any kind of help.

    Seems some kernel headers are missing on your system (dev-setup), see: http://fxr.watson.org/fxr/source/net/if.h -- this is where "IFCAP_HWSTATS" is/should be defined: "head/sys/net/if.h" -- Did you install/download kernel headers? – MWiesner Nov 23 '15 at 19:32

When inspecting version 9.x of the if.hfile in different versions of the FreeBSD kernel, "IFCAP_HWSTATS" was missing. In Version 10 it was present again, maybe FreeBSD developers have changed or broken this in version 9.x? As the latest driver by Intel in version 2.8.2 requires this declaration the compilation breaks - sadly.

For this reason, you should try with driver version 2.5.25, as the driver description at https://downloadcenter.intel.com/product/83949/Intel-Ethernet-Converged-Network-Adapter-X710-Series states:

This driver is intended for FreeBSD 7.2 or later

By contrast, the driver for driver 2.8.2 seems to be written for FreeBSD 10.x and upwards only.

Hope this helps.

    With this version of the driver, the build works under FreeBSD 9.3-RELEASE-p30. Now I have to test this driver with my FreeNAS installation - hopefully this will work! – rzo Nov 23 '15 at 20:09
