2016-08-31qed: Clear dcbx memory buffers before the usage.Sudarsana Reddy Kalluru
This patch takes care of clearing the uninitialized buffer before using it. 1. pfc pri-enable bitmap need to be cleared before setting the requested enable bits. Without this, the un-touched values will be merged with requested values and sent to MFW. 2. The data in app-entry field need to be cleared before using it. 3. Clear the output data buffer used in qed_dcbx_query_params().

2016-08-31qed: Set selection-field while configuring the app entry in ieee mode.Sudarsana Reddy Kalluru
Management firmware requires the selection-field (SF) to be set for configuring the application/protocol entry in IEEE mode. Without this setting, the app entry will be configured incorrectly in MFW.

2016-06-08qed: Add support for query/config dcbx.Sudarsana Reddy Kalluru
Query API reads the dcbx data from the device shared memory and return it to the caller. The config API configures the user provided dcbx values on the device, and initiates the dcbx negotiation with the peer.

2016-05-17qed: add support for dcbx.Sudarsana Reddy Kalluru
This patch adds the necessary driver support for Management Firmware to configure the device/firmware with the dcbx results. Management Firmware is responsible for communicating the DCBX and driving the negotiation, but the driver has responsibility of receiving async notification and configuring the results in hw/fw. This patch also adds the dcbx support for future protocols (e.g., FCoE) as preparation to their imminent submission.
