Create the necessary enumerations to declare all of that. Include them in the currently-almost-empty phy_channels structure which until now only declared the supported channels as bitfields. The PRF is declared in a union as this clearly is a parameter that does not apply to most of the protocols. It is very likely that other parameters will get added in the future to further define specific protocols and the union will likely be a good location for them.
