iwlwifi: debugFs to enable/disable HT40 support
Add debugfs file to enable/disable HT40(40MHz) channel support. By default, 40MHz is supported if AP can support the function. By echo "1" to "disable_ht40" file, iwlwifi driver will disable the 40MHz support and only allow 20MHz channel. Because the information exchange happen during association time, so enable/disable ht40 channel only can be performed when it is not associated with AP.
