skb_put - add data to a buffer
unsigned char * skb_put(struct sk_buff * skb, unsigned int len);
buffer to use
amount of data to add
This function extends the used data area of the buffer. If this would exceed the total buffer size the kernel will panic. A pointer to the
first byte of the extra data is returned.

Allocates an skb that will contain the message to send to user space over the messaging pipe and initializes it, copying the payload.
Once this call is done, you can deliver it with wimax_msg_send.
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
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.
