From: Chien-Hsun Liao <[email protected]> Update BB and RF channel settings. The old settings are not compatible with most of the chips now. To swtich to a target channel correctly, many of the PHY parameters needs to be modified.
For BB, the DAC clock setting, CCK tx filter coefficient and OFDM dfir should be updated in order to meet 802.11 standards of spectral mask. CCK trx settings should be modified based on different band, because the CCK signals are not allowed in 5G bands. For RF, subband setting should be corrected, ch-140 ~ ch-144 is in band-3 instead of band-4. Also rx amplifier should be set to different values in different bandwidth, otherwise the rx sensitivity will degrade. Note the settings are based on phy parameter v27 table, should be applied together to make sure it work.
