From: Xinming Hu <[email protected]> When assocaiting to an AP , mwifiex set supported data rates based on target AP's capability. For 5G AP(11a mode), a/n/ac mode would possibly be set. However, for some chips which dont support 11AC mode current config_bands will be used instead.
For example, if we join an IBSS in 11b mode ,adapter->config_bands will be set to 1(11b mode). Then we leave IBSS ,and try to connect 5G a/n mode AP. At this time , only 11b mode data rates will be supported in assoc request , which result in assoc failure with reason code 18: Association denied due to requesting station not supporting all rates. This patch fix such a cornel case, by adding additional check for current chip's 11ac capability.
