Hi,

I want o create wifi driver custom ioctol command. How can I find which group, number I can use without conflicting with
 the existing ones? 

I searched ioctl.h, ieee80211_ioctl.h, but it is not obvious about the convention of how to define the custom ioctl 
index.

thanks,

Yurong

Re: custom ioctl command index

Custom driver ioctls should be wrapped in an SIOCSDRVSPEC / SIOCGDRVSPEC ioctl.
