   4 Subject: [PATCH 1/2] mesh: add VHT_CHANWIDTH_USE_HT to max_oper_chwidth
   5
   6 Channel width in VHT mode refers HT capability when
   7 the width goes down to below 80MHz, hence add checking
   8 HT channel width to its max operation channel width.
   9 So that mesh has capable to select bandwidth below 80Mhz.
