[PATCH V1 1/3] net/mlx4_en: Set correct port parameters during device initialization
From: Yevgeny Petrilin <hidden>
Date: 2012-06-25 13:24:22
Subsystem:
mellanox ethernet driver (mlx4_en), mellanox mlx4 core vpi driver, networking drivers, the rest · Maintainers:
Tariq Toukan, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
Set valid port parameters: MTU and flow control configuration when configuring the port during HW device initialization, prior to the net device open() being called. Using invalid parameters (such as all zeros) could lead to bad firmware behavior.
