32 to function. Application firmware can be located either on the host file system
33 or in the device flash (if supported by management firmware).
35 Firmware files on the host filesystem contain card type (`AMDA-*` string), media
36 config etc. They should be placed in `/lib/firmware/netronome` directory to
37 load firmware from the host file system.
39 Firmware for basic NIC operation is available in the upstream
