Hi Jakub, The firmware config file contains information on how the firmware should distribute the hardware resources among NIC and Upper Layer Drivers(ULD), like iWARP, crypto, filtering, etc. The firmware image comes with an in-built default config file that distributes resources among the NIC and all the ULDs. However, in some cases, where we don't want to run a particular ULD, or if we want to redistribute the resources, then we'd modify the firmware config file and then firmware will redistribute those resources according to the new configuration. So, if firmware finds this custom config file in flash, it reads this first. Otherwise, it'll continue initializing the adapter with its own in-built default config file. Thanks -Ganji Aravind.
