This patch adds support for ethernet rxtx mode to the driver. The feature
is enabled via a new module parameter. If enabled to driver will enable
the feature on a per vif basis if all other requirements were met.

Testing on a IPQ4019 based hardware shows a increase in TCP throughput
of ~20% when the feature is enabled.

Hello,

Do you have an idea of where this improvement comes from?  Is it CPU load on
the host, or does firmware somehow work better in this mode?

And, does UDP also show improvement?

Thanks,
Ben
