Subject: [PATCH 4.9 16/94] net/mlx5e: Fix ethtool pause support and advertise reporting

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gal Pressman <galp@...lanox.com>


[ Upstream commit e3c19503712d6360239b19c14cded56dd63c40d7 ]

Pause bit should set when RX pause is on, not TX pause.
Also, setting Asym_Pause is incorrect, and should be turned off.
