It's related to BT coexistance or radar... prima expects this payload with it

#define WLAN_HAL_MAX_AVOID_FREQ_RANGE           4

typedef PACKED_PRE struct PACKED_POST
{
   tANI_U32     startFreq;
   tANI_U32     endFreq;
}  tHalFreqRange, *tpHalFreqRange;

typedef PACKED_PRE struct PACKED_POST
{
   tANI_U32         avoidCnt;
   tHalFreqRange    avoidRange[WLAN_HAL_MAX_AVOID_FREQ_RANGE];

Basically wcn firmware can propose up to 4 frequency ranges to not use
for whatever reason... prima looks like it tries to disable channels
accordingly.
