Subject: [PATCH net-next 0/3] Add destination MAC address to ethtool flow steering

From: Yan Burman <>

In vSwitch configuration it is often beneficial to create flow steering
rules for L3/L4 traffic based on VM port. This requires destination MAC
address of that port to be present. Note that today the mlx4_en driver 
adds the mac address of itself to the flow spec, where under the new
ethtool flag suggested here it doesn't.

It may also be useful in macvlan devices.

These patches add kernel support for the new field (does not break old
userspace compatibility, so new ethtool will work on old kernels and
old ethtool will work with new kernels).

Also present here is the ethtool userspace patch.

See more details here http ://
