Subject: [PATCH 2/2] mesh: implement use of VHT20 config in mesh mode
|
|
|
|
mesh in VHT mode is supposed to be able to use any bandwidth
|
|
that 11ac supports, but we don't have a way to set VHT20
|
|
although there are parameters that are supposed to be used.
|
|
This patch along with the patch of
|
|
"mesh: add VHT_CHANWIDTH_USE_HT to max_oper_chwidth" makes mesh
|
|
available to use of any bandwidth using combination of
|
|
existing parameters like below shown.
|
|
|
|
VHT80:
|
|
default
|
|
do not set any parameters
|
|
VHT40:
|
|
max_oper_chwidth = 0
|
|
VHT20:
|
|
max_oper_chwidth=0
|
|
disable_ht40=1
|
|
HT40:
|
|
disable_vht = 1
|
|
HT20:
|
|
disable_ht40 = 1
|
|
disable HT:
|
|
disable_ht = 1
|
