Hi Eelco, Thanks for the patch! Looks reasonable. One comment is that it's better to explicitly initialize the flag in common_construct. I see that we doesn't initialize 'started' flag, but this might be fixed too. More comments inline. Best regards, Ilya Maximets.

I see. There was a 2 byte hole after 'hwaddr' and with your patch it moved earlier moving the 'hwaddr' from byte 4 to byte 6. Maybe you could add a /* 1 pad byte here. */ after the new flag? Best regards, Ilya Maximets.

Currently, OVS does not register and therefore not handle the interface reset event from the DPDK framework. This would cause a problem in cases where a VF is used as an interface, and its configuration changes. As an example in the following scenario the MAC change is not detected/acted upon until OVS is restarted without the patch applied: $ echo 1 > /sys/bus/pci/devices/0000:05:00.1/sriov_numvfs $ ovs-vsctl add-port ovs_pvp_br0 dpdk0 -- \ set Interface dpdk0 type=dpdk -- \ set Interface dpdk0 options:dpdk-devargs=0000:05:0a.0 $ ip link set p5p2 vf 0 mac 52:54:00:92:d3:33 Signed-off-by: Eelco Chaudron <echaudro@redhat.com> --- lib/netdev-dpdk.c | 49 +++++++++++++++++++++++++++++++++++++++++++++-- 1 file changed, 47 insertions(+), 2 deletions(-)
