[Tamizh] I'm planning to do this check in iw itself and converting into a value, 

iw command will looks like below

iw btcoex enable [<be> <bk> <vo> <vi> <mgmt><beacon>]

If anything other than this given by user will be rejected and will not forward to cfg80211.
Do you have any concern on this?

[Tamizh] Yes, we can have this for checking invalid or the value is greater the driver support value
