394  * This function returns TRUE if both the chanspec can co-exist in PHY.
395  * Addition to primary20 channel, the function checks for side band for 2g 40 channels
485  * Channel Factor for the starting frequence of 2.4 GHz channels.
491  * Channel Factor for the starting frequence of 5 GHz channels.
497  * Channel Factor for the starting frequence of 4.9 GHz channels.
505  *  No of sub-band vlaue of the specified Mhz chanspec
523  * Convert chanspec to ascii string
536  * Convert chanspec to ascii string
549  * Convert ascii string to chanspec
558  * Convert ascii string to chanspec
593  * 20MHz channels this is just the channel number. For 40MHz or wider channels
626  * channels this is just the chanspec. For 40MHz or wider channels it is the
651  * frequencies from 5 - 6 GHz, and 2.407 GHz is assumed for 2.4 - 2.5 GHz.
660  * -1 is returned if the start_factor is WF_CHAN_FACTOR_2_4_G and the
664  * Reference 802.11-2016, section 17.3.8.3 and section 16.3.6.3
688  * Odd start_factors produce channels on .5 MHz boundaries, in which case
690  * -1 is returned for an out of range channel.
692  * Reference 802.11-2016, section 17.3.8.3 and section 16.3.6.3
708  *	primary_channel - primary 20Mhz channel
709  *	center_channel   - center frequecny of the 80Mhz channel
718  * Convert ctl chan and bw to chanspec
734  *    primary_20mhz - Primary 20 MHz channel
735  *    chan0_80MHz - center channel number of one frequency segment
736  *    chan1_80MHz - center channel number of the other frequency segment
739  * The primary channel must be contained in one of the 80MHz channels. This routine
744  * Refer to 802.11-2016 section 22.3.14 "Channelization".
750  * Returns the center channel of the primary 80 MHz sub-band of the provided chanspec
754  * @return	center channel number of the primary 80MHz sub-band of the input.
761  * Returns the center channel of the secondary 80 MHz sub-band of the provided chanspec
765  * @return	center channel number of the secondary 80MHz sub-band of the input.
771  * Returns the chanspec for the primary 80MHz sub-band of an 160MHz or 80+80 channel
775  * @return	An 80MHz chanspec describing the primary 80MHz sub-band of the input.
782  * Returns the chanspec for the secondary 80MHz sub-band of an 160MHz or 80+80 channel
783  * The sideband in the chanspec is always set to WL_CHANSPEC_CTL_SB_LL since this sub-band
788  * @return	An 80MHz chanspec describing the secondary 80MHz sub-band of the input.
794  * For 160MHz or 80P80 chanspec, set ch[0]/ch[1] to be the low/high 80 Mhz channels
796  * For 20/40/80MHz chanspec, set ch[0] to be the center freq, and chan[1]=-1
