From 62259ac4b36e348077635e673f253cc139dd6032 Mon Sep 17 00:00:00 2001 From: Somnath Kotur Date: Wed, 7 Sep 2016 19:57:51 +0530 Subject: [PATCH] be2net: Add privilege level check for OPCODE_COMMON_GET_EXT_FAT_CAPABILITIES SLI cmd. Driver issues OPCODE_COMMON_GET_EXT_FAT_CAPABILITIES cmd during init which when issued by VFs results in the logging of a cmd failure message since they don't have the required privilege for this cmd. Fix by checking privilege before issuing the cmd. Also fixed typo in CAPABILITIES. Signed-off-by: Somnath Kotur Signed-off-by: Sriharsha Basavapatna Signed-off-by: David S.
