Subject: [PATCH wpan-next v2 2/5] net: ieee802154: Give more details to the core about the channel configurations
In order to let the core derive eg. the symbol duration for a given
channel, it needs to know which protocol is being used, on which band,
and eventually more details such as the mean PRF in the case of UWB.
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.
