Netanel Belgazal says:

====================
net: update ena ethernet driver to version 1.2.0

This patchset contains some new features/improvements that were added
to the ENA driver to increase its robustness and are based on
experience of wide ENA deployment.

Change log:

V2:
* Remove patch that add inline to C-file static function (contradict coding style).
* Remove patch that moves MTU parameter validation in ena_change_mtu() instead of
using the network stack.
* Use upper_32_bits()/lower_32_bits() instead of casting.
