Subject: [PATCH 03/19] wpa_supplicant: handle HT40 and mode downgrade in AP
|
|
mode
|
|
|
|
This patch adds some missing pieces to the interface configuration
|
|
of AP/mesh mode in wpa_supplicant.
|
|
- check for secondary channel and HT40 capability
|
|
- try to downgrade to 11b if 11g is not available
|
|
Especially with the HT40 check, this code now performs all settings,
|
|
which the deleted/duplicated mesh code did.
