sorry for not been so clear.
ED/CCA is used to control tx power according to the CCA MIB counters (e.g do not
transmit if the channel busy time is higher than 90% for given amount of time
in a row).
As already done in commit 643749d4a82b ("mt76: mt76x02: disable ED/CCA by default"),
this patch adds the possibility to enable/disable the processing according to an
entry in the debugfs. The reason behind this patch is ED/CCA caused
instability in the past so it could be useful to disable it.
