====================
mlx4_en XDP TX improvements

This patchset contains performance improvements
to the XDP_TX use case in the mlx4 Eth driver.

Patch 1 is a simple change in a function parameter type.
Patch 2 replaces a call to a generic function with the
  relevant parts inlined.
Patch 3 moves the write of descriptors' constant values
  from data path to control path.
