bng_en: Add initial interaction with firmware Query firmware with the help of basic firmware commands and cache the capabilities. With the help of basic commands start the initialization process of the driver with the firmware. Since basic information is available from the firmware, register with devlink.

bng_en: Add backing store support Backing store or context memory on the host helps the device to manage rings, stats and other resources. Context memory is allocated with the help of ring alloc/free functions.

bng_en: Add resource management support Get the resources and capabilities from the firmware. Add functions to manage the resources with the firmware. These functions will help netdev reserve the resources with the firmware before registering the device in future patches. The resources and their information, such as the maximum available and reserved, are part of the members present in the bnge_hw_resc struct. The bnge_reserve_rings() function also populates the RSS table entries once the RX rings are reserved with the firmware.

bng_en: Initialize default configuration Query resources from the firmware and, based on the availability of resources, initialize the default settings. The default settings include: 1. Rings and other resource reservations with the firmware. This ensures that resources are reserved before network and auxiliary devices are created. 2. Mapping the BAR, which helps access doorbells since its size is known after querying the firmware. 3. Retrieving the TCs and hardware CoS queue mappings.
