NAME
       wimax_msg_send - Send a pre-allocated message to user space

SYNOPSIS
       int wimax_msg_send(struct wimax_dev * wimax_dev, struct sk_buff * skb);

ARGUMENTS
       wimax_dev
	   WiMAX device descriptor

       skb

	   struct sk_buff returned by wimax_msg_alloc. Note the ownership of skb is transferred
	   to this function.

RETURNS
       0 if ok, < 0 errno code on error

DESCRIPTION
       Sends a free-form message that was preallocated with wimax_msg_alloc and filled up.

       Assumes that once you pass an skb to this function for sending, it owns it and will
       release it when done (on success).

IMPORTANT
       Don't use skb_push/skb_pull/skb_reserve on the skb, as wimax_msg_send depends on skb->data
       being placed at the beginning of the user message.

       Unlike other WiMAX stack calls, this call can be used way early, even before wimax_dev_add
       is called, as long as the wimax_dev->net_dev pointer is set to point to a proper net_dev.
       This is so that drivers can use it early in case they need to send stuff around or
       communicate with user space.
