This file defines the types and contants used to implement 49* the p80211 request/confirm/indicate interfaces on Linux. The 50* request/confirm interface is, in fact, normally implemented as an 51* ioctl. The indicate interface on the other hand, is implemented 52* using the Linux 'netlink' interface. 53* 54* The reason I say that request/confirm is 'normally' implemented 55* via ioctl is that we're reserving the right to be able to send 56* request commands via the netlink interface. This will be necessary 57* if we ever need to send request messages when there aren't any 58* wlan network devices present (i.e. sending a message that only p80211 59* cares about. 60* -------------------------------------------------------------------- 61*/ 62 63#ifndef _P80211IOCTL_H 64#define _P80211IOCTL_H 65 66/* p80211 ioctl "request" codes.
