4 Subject: [PATCH 2/2] mesh: implement use of VHT20 config in mesh mode
5  
6 mesh in VHT mode is supposed to be able to use any bandwidth
7 that 11ac supports, but we don't have a way to set VHT20
8 although there are parameters that are supposed to be used.
9 This patch along with the patch of
10 "mesh: add VHT_CHANWIDTH_USE_HT to max_oper_chwidth" makes mesh
11 available to use of any bandwidth using combination of
12 existing parameters like below shown.
13  
14 VHT80:
15 default
16 do not set any parameters
17 VHT40:
18 max_oper_chwidth = 0
19 VHT20:
20 max_oper_chwidth=0
21 disable_ht40=1
22 HT40:
23 disable_vht = 1
24 HT20:
25 disable_ht40 = 1
26 disable HT:
27 disable_ht = 1
