[dpdk-dev] [PATCH 01/28] bnxt: add hwrm_func_cfg_input/output structures

Tue Mar 28 05:48:36 CEST 2017


This patch adds hwrm_func_cfg API which allows the configuration
of a child VF by its parent PF driver. It an also be used to configure a
PF by its corresponding PF driver.

+ * Description: This command allows configuration of a PF by the corresponding
+ * PF driver. This command also allows configuration of a child VF by its parent
+ * PF driver. The input FID value is used to indicate what function is being
+ * configured. This allows a PF driver to configure the PF owned by itself or a
+ * virtual function that is a child of the PF. This command allows to reserve
+ * resources for a VF by its parent PF. To reverse the process, the command
+ * should be called with all enables flags cleared for resources. This will free
+ * allocated resources for the VF and return them to the resource pool. If this
+ * command is requested by a VF driver to configure or reserve resources, then
+ * the HWRM shall fail this command. If default MAC address and/or VLAN are
+ * provided in this command, then the HWRM shall set up appropriate MAC/VLAN
+ * filters for the function that is being configured. If source properties
+ * checks are enabled and default MAC address and/or IP address are provided in
+ * this command, then the HWRM shall set appropriate source property checks
+ * based on provided MAC and/or IP addresses. The parent PF driver should not
+ * set MTU/MRU for a VF using this command. This is to allow MTU/MRU setting by
+ * the VF driver. If the MTU or MRU for a VF is set by the PF driver, then the
+ * HWRM should ignore it. A function's MTU/MRU should be set prior to allocating
+ * RX VNICs or TX rings. A PF driver calls hwrm_func_cfg to allocate resources
+ * for itself or its children VFs. All function drivers shall call hwrm_func_cfg
+ * to reserve resources. A request to hwrm_func_cfg may not be fully granted;
+ * that is, a request for resources may be larger than what can be supported by
+ * the device and the HWRM will allocate the best set of resources available,
+ * but that may be less than requested. If all the amounts requested could not
+ * be fulfilled, the HWRM shall allocate what it could and return a status code
+ * of success. A function driver should call hwrm_func_qcfg immediately after
+ * hwrm_func_cfg to determine what resources were assigned to the configured
+ * function. A call by a PF driver to hwrm_func_cfg to allocate resources for
+ * itself shall only allocate resources for the PF driver to use, not for its
+ * children VFs. Likewise, a call to hwrm_func_qcfg shall return the resources
+ * available for the PF driver to use, not what is available to its children
+ * VFs.
