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

21
23 Sends a free-form message that was preallocated with wimax_msg_alloc
24 and filled up.
25
26 Assumes that once you pass an skb to this function for sending, it owns
27 it and will release it when done (on success).
28
30 Don't use skb_push/skb_pull/skb_reserve on the skb, as wimax_msg_send
31 depends on skb->data being placed at the beginning of the user message.
32
33 Unlike other WiMAX stack calls, this call can be used way early, even
34 before wimax_dev_add is called, as long as the wimax_dev->net_dev
35 pointer is set to point to a proper net_dev. This is so that drivers
36 can use it early in case they need to send stuff around or communicate
37 with user space.
