Re: [Madwifi-devel] Madwifi and ETSI EN 300 328 V1.8.1

Hello Jörg​,

Yes, there is similar code in MadWifi. Just look
for AR5212_CCA_MAX_GOOD_VALUE and AR5416_CCA_MAX_GOOD_VALUE. There is a
little problem with the code - MadWifi uses the same value for 2GHz and
5GHz, whereas the changes in ath9k use separate limits for different bands.

I don't want to change any MadWifi logic that cannot be trivially tested.
We don't have any active userbase. If we do it wrong, nobody would tell us.
I would rather verify that the change applies to all chipsets supported by
ath5k and ath9k. If you want changes in MadWifi, please make sure they are
in ath5k and ath9k for the corresponding chipsets.

ath5k uses the same value for both bands, AR5K_TUNE_CCA_MAX_GOOD_VALUE
equal to -95. It would need to be changed to support per-band limits.

ath9k always uses per-band limits. But the limits are wildly different
across chipsets, ranging from -116 to -60.
