Subject: wil6210: send connect request IEs to FW also for non-secure connection
X-Git-Tag: v3.18-rc1~115^2~144^2~65
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ac4acdb7af7b5f1f197e7c3fdce13b6aa72c29c6;p=karo-tx-linux.git

wil6210: send connect request IEs to FW also for non-secure connection

Driver is sending connect request IEs to FW only for secure connection and
ignores them for non-secure connection.
This is fixed by always sending the IEs to FW upon connect request
