Libra units can be upgraded by loading new Master Image Files to the unit. A Master Image File
contains all software components required by the processors running on the units. These
components are the main CPU, the FPGA, and the DSP. Upgrades may be skipped unless specified
otherwise on the Wi-LAN web site, when upgrading to newer Master Image versions.
