When verifying WNM BSS transition function, it's possible to
ask peer STA to transition across multiple band. Some vendor
BTM implementation is needed to check country IE to get all
supported band channel info. Without full channel list in
country IE, it cannot make a transition across multiple band.
To solve the interop issue, let country IE take all supported
band channel info when the specific vendor OUI is detected in
association request.
