Add a control private flag in ethtool for enable/disable
TX push feature.

I think it's a pretty standard feature for NICs which also support RDMA.
Mellanox/nVidia has it (or at least it the previous gen HW did),
Broadcom's bnxt driver does it as well.

Can we make this a standard knob via ethtool? Not entirely sure under
which switch, maybe it's okay to add it under -g? Perhaps we need a new
command similar to -k but for features contained entirely to the driver?
