Hi Garrett.
Thanks a lot.
Where can I download the updated "sysfs.h" file?
Regards,
Alex Liptsin

Hello.
I have FreeBSD 9.1 installed.
There is mellanox adapter inside.
[root@qa-h-vrt-030-006 ~]# pciconf -lv |grep mlx4 -A 3

OFED support is already compiled.
I try to add pkeys on ib0 port.
Usually in Linux I did:
echo 0x800c > /sys/class/net/ib0/create_child
ifconfig -a
To Make sure you see a new interface: ib0.800c
How can I do it on FreeBSD? There is no "/sys/class/net/ib0/create_child" d=
irectory.
Hi Alex!
For all sysfs entries there *should* be a corresponding sysctl for it. =
Do sysctl -Na | grep create_child and you might find the node that you seek=
. After that all you need to do is call sysctl <node>=3D0x800c and it shoul=
d achieve the same thing as setting the sysfs node.
Please note that you must be the patch attached to http://www.freebsd.o=
rg/cgi/query-pr.cgi?pr=3Dkern/174213 in order for things to function proper=
ly as the sysfs handling code is still broken on HEAD. I've CCed Jeff Rober=
son about it a few times, and asked for assistance from Xin as well as I ha=
ven't gotten any feedback from Jeff.
Thanks,
-Garrett
