From 95f56e7aa807e9eec241a5b70f0695b2514b5ad5 Mon Sep 17 00:00:00 2001 From: Yevgeny Petrilin Date: Thu, 29 Dec 2011 07:42:39 +0000 Subject: [PATCH] mlx4_core: limiting VF port options At the moment VFs can only operate in Eth mode. In addition we don't want the VF to attempt link sensing, so we block this option as well. Signed-off-by: Yevgeny Petrilin Signed-off-by: David S.
