wimax_msg_send - Send a pre-allocated message to user space
int wimax_msg_send(struct wimax_dev * wimax_dev, struct sk_buff * skb);
WiMAX device descriptor
struct sk_buff returned by wimax_msg_alloc. Note the ownership of skb is transferred
to this function.
0 if ok, < 0 errno code on error
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).
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.
