From 297e1cf29eac13d3e5bb896d18c64a50b6bb48eb Mon Sep 17 00:00:00 2001 From: Ariel Levkovich Date: Sun, 29 Jan 2017 18:56:17 +0200 Subject: net/mlx4_en: Adding support of turning off link autonegotiation via ethtool This feature will allow the user to disable auto negotiation on the port for mlx4 devices while setting the speed is limited to 1GbE speeds. Other speeds will not be accepted in autoneg off mode. This functionality is permitted providing that the firmware is compatible with this feature. The above is determined by querying a new dedicated capability bit in the device. Signed-off-by: Ariel Levkovich Signed-off-by: Tariq Toukan Signed-off-by: David S.
