Documentation for "fw.mgmt":

fw.mgmt
-------

Control unit firmware version. This firmware is responsible for house
keeping tasks, PHY control etc. but not the packet-by-packet data path
operation.

To me, platform management would need a new name, as the term "fw.mgmt"
has already been used by multiple drivers.

Jake
