The values should be either set or unset - CEE selection field must be set regardless CEE/IEEE mode - Fail the dcbx query for VF interfaces - Semantic changes Signed-off-by: Rasesh Mody --- drivers/net/qede/base/ecore.h | 3 + drivers/net/qede/base/ecore_dcbx.c | 375 ++++++++++++++------------------- drivers/net/qede/base/ecore_dcbx_api.h | 1 + drivers/net/qede/base/ecore_dev.c | 24 ++- 4 files changed, 185 insertions(+), 218 deletions(-) diff --git a/drivers/net/qede/base/ecore.h b/drivers/net/qede/base/ecore.h index b1b0a2ed..b41ff4a2 100644 --- a/drivers/net/qede/base/ecore.h +++ b/drivers/net/qede/base/ecore.h @@ -373,6 +373,9 @@ struct ecore_hw_info { u32 port_mode;
