From: Xinming Hu <huxm@xxxxxxxxxxx>
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.
