Actually 40GHz is less a problem in 5GHz than in 2.4GHz since in 2.4GHz
I need to have a "Coexistence mechanism", which is not required in 5GHz.
This Coexistence mechanism is apparently implemented by one OEM under the
name "Clear Channel Assessment (CCA)".
In short, I don't think there is any special issue with 40MHz in 5GHz, but
I may miss something here... In any case, I have no problem with sending
a patch that allows 5GHz in 20MHz for the moment.
I can also have a look at the EEPROM in our NICs which is supposed to have
all the needed limitations. Details to follow tomorrow.
